Arthur Fils vs. Luca Van Assche

Arthur Fils and Luca Van Assche will face off for the first time on the ATP Tour on Friday. Both players have advanced to the semi-finals of the Next Gen ATP Finals presented by NEOM, by using their physical make-up in two very contrasting ways. In the three matches of pool play, Van Assche has played the most physical brand of tennis, leading all competitors with the most distance covered, highest workload output, and largest total of explosive movements. He closed out the group stage by playing the second-longest match in Next Gen ATP Finals history, recording a Physicality Index rating of 10, the second-highest rating in tournament history, only behind his opponent in that match, Alex Michelson.

What we know from the data is that Van Asche has no problem responding to high volume and intensity matches, as earlier this year he defeated three-time major winner Stan Wawrinka in a match that was comparable to the output of last nights match against Michelson. He came back the next day and pushed Novak Djokovic to three sets, again pushing his PI rating upward of 9.0.

Fills has spent 25 minutes less of active hitting time on court than Van Assche during the course of the first three matches. His first match against Luca Nardi was his most physical match of the Next Gen ATP Finals, recording a Physical Intensity rating of 7.6. Dominic Stricker was able to force Fils into executing his highest number of explosive movements per minute in their four-set match, forcing him to change direction more often in that match.

Keys to Match

Both of these players are physically prepared to compete in the semi-final match-up. They have both proven they can compete physically with the best players in the world, in consecutive matches back to back. The tactical game plan is going to dictate a lot of how the physicality of this match looks. In the one loss Van Assche experienced this week, he moved at a much slower rate than in his other two wins. The amount of high-speed distance he covered was way below his average for the season. That was largely due in part to Medjedovic dictating early in the rallies, keeping the rally count below his season average of 4.5 shots per rally. When Fils is playing his best tennis, he is dictating play with his forehand left of centre, and hitting his forehand over 60% of the time. Van Assche is going to need to get him changing direction more frequently. In the matches Fils has lost this year, he has been forced to change direction almost 25% more.

Hamad Medjedovic vs. Dominic Stricker

Hamad Medjedovic and Dominic Stricker are tactically looking to accomplish the same thing. Strike early and strike often. In their Next Gen ATP Finals matches, both players are averaging 5% more of their points in attack than their opponents. Both players have executed the least amount of high-speed distance and explosive movements in the tournament.

Medjedovic has shown that he is a competitor and he is not going to shy away from the physical pain that comes with going deep into the match. He overcame cramping in his first-round match against Michelson, and followed that up with another tough four-set match against Van Assche.

Keys to Match

Win or lose, we know one thing, both these players are going to try and keep the points short. They are both looking to serve big and take advantage of the balls in the mid-court. Look for Medjedovic to dictate with his forehand, forcing Stricker to have to defend his forehand on the run. Stricker will look to push Medjedovic off the baseline with good depth and then use his lefty forehand to make Medjedovic defend outside the singles sideline with his backyard. Both players have the ability to use their offense to move forward and finish the points off at the net. I would not expect very high PI metrics for this match, as the rallies will look to be short.

At the close of a standout season in which he won his first ATP Tour title in Lyon, Arthur Fils entered the Next Gen ATP Finals presented by NEOM at a career-high Pepperstone ATP Ranking of No. 36.

But what is the 19-year-old like off the court? ATPTour.com caught up with the Jeddah top seed for a Q&A that covered his post-tennis career plans, his favourite sports and a holiday adventure.

If you could have dinner with three people, who would they be and why?
Cristiano Ronaldo first, because for me he’s the best footballer who exists in the world. I would say also Michael Jordan, because I’ve watched him a lot. And, third, I’m going to say The Rock. 

So you’d say Ronaldo is better than Messi?
For me, yeah. My coach, Sergi Bruguera, loves Messi. So we have a little fight about it.

If you weren’t a tennis player, what job would you want and why?
An actor, for sure. That’s what I’m going to do after my career, for sure. Action movies, like Michael B. Jordan.

If you had to choose between attending a music concert or a sporting event, what would you choose and why?
Sports. I don’t like to go to concerts. To be in the crowd and jumping, I don’t like it. If I’m going, I have to be sitting. Of course I enjoy with friends and everything. But to jump and to be close with all the people in the crowd, that’s not something that I like. And I love sports.

What sports would you want to watch?
Soccer for sure. I support PSG. And probably basketball. I would also love to try Formula 1, in the paddock.

What is one of the most interesting things you have done in your life?
I went swimming with dolphins two weeks ago, in Mauritius. I’d never been to Mauritius for a holiday, so I swam with dolphins.

How well do you know the other competitors here in Jeddah? Are you good friends with anyone?
I’m very close to Luca Van Assche because we’ve played since we were very young together. So Luca, and the other guys here are very nice… Alex Michelsen, Abdullah Shelbayh. Everyone is very nice. We have some good times and we are enjoying it.

Like every year at the Next Gen ATP Finals, the tournament will be trialling a lot of different rules and innovations. What are your thoughts on them? Is there one that you’re interested to try out?
No warm-ups. It’s going to be good or very bad. I don’t know if it’s possible to come on the court without a warm-up. You don’t play, you don’t hit one ball. So first serve, maybe you’re going to frame the ball or double fault. Some guys are going to be very good, and probably some others are going to be broken every time in the first game. Let’s see.

Is there another rule that you’re more excited about?

The free fan movement. I will love to see. I heard that it’s not behind us and in front of us, just on the side, so this should be good. It’s nice because it’s like in basketball and American football or soccer. It’s quite nice. We’ll see how it is.

You’ve had a great season, including winning your first ATP Tour title in Lyon. What is the biggest thing you learned from this year?
Never quit, because things can change very quickly. I would say that’s the biggest thing that I’ve learned this year. I’ve played some matches and things were changing so quick, my opponent or I didn’t quit, and it was a great match, and we are enjoying playing this type of match. So never quit.

Rafael Nadal announced on social media Friday that he will make his return in the first week of the 2024 season at the Brisbane International presented by Evie.

“Hello everyone. After a year away from competition, it’s time to come back,” Nadal said in Spanish in a video that has garnered millions of views. “It will be in Brisbane the first week of January. I’ll see you there.”

Two weeks ago the Spaniard confirmed that he would make his return. Now he knows where and when.

The former World No. 1 played two tournaments this year — the United Cup and Australian Open — before missing the rest of the season due to an injury to the iliopsoas muscle in his left leg, for which he later underwent surgery.

Nadal will compete in Brisbane for the second time. The lefty played the ATP 250 in 2017, when he advanced to the quarter-finals before losing to then-World No. 3 Milos Raonic in three sets.

The tournament has not yet announced Nadal’s participation, but organisers have revealed that Holger Rune, Ben Shelton, Grigor Dimitrov and Andy Murray will also compete in the event. 

Friday evening’s semi-finals at the Next Gen ATP Finals presented by NEOM will see a pair of first-time Lexus ATP Head2Head meetings. First is an all-French battle between Arthur Fils and Luca Van Assche, followed Hamad Medjedovic vs. Dominic Stricker.

[1] Arthur Fils (FRA) vs. [2] Luca Van Assche (FRA)

Top seed Fils and second seed Van Assche played once before at the junior level, in 2021. In the final of Roland Garros, their home Grand Slam, Van Assche earned a straight-sets victory. By becoming the first Frenchmen to reach the semi-finals in the six-year history of the Next Gen ATP Finals, they have set up another high-stakes encounter in Jeddah.

Fils enters as winner of the Green Group with a perfect 3-0 record. This year’s Lyon champion leads the field in both second-serve points won (60%) and return games won (9 of 35, 26%). Van Assche, who finished second in the Red Group at 2-1, is second in return games won (9 of 37, 24%) but has faced a tournament-high 37 break points, saving 31 of them.

With three matches under their belts, both players are now accustomed to the innovations and new rules on trial at the event — including no on-court warm-up and a reduced shot clock.

“It is exciting to have new rules and I am adapting after three matches,” Van Assche said. “I think most of the rules are pretty cool. The no warm-up is a bit difficult.”

[3] Dominic Stricker (SUI) vs. [6] Hamad Medjedovic (SER)

While Stricker and Medjedovic are not countrymen, their relationship goes back many years to their early junior days.

“I’ve known Dominic for a long time,” Medjedovic said after beating Arab hope Abdullah Shelbayh to secure his semi-final place. “He’s a great player and a great guy obviously. I think it’s going to be a great match and I’m happy to be in the semis.”

The Serbian leads the Jeddah field in a number of key metrics on both serve and return, including aces (45), service games won (37 of 39, 95%) and points won against first serve (32%). Those numbers added up to a perfect 3-0 record and a first-place finish in the Red Group.

Stricker posted a 1-2 record in the Green Group and advanced with a better percentage of sets won (45%) than Italians Flavio Cobolli and Luca Nardi, who were also 1-2. While he has not sustained top form so far in Jeddah, he has the advantage of experience: The lone returning competitor at this year’s Next Gen ATP Finals, Stricker also reached the semis last season in Milan. He has picked up considerable big-match experience since then, with a run to the US Open fourth round that helped him achieve a career-high Pepperstone ATP Ranking of No. 88 in October.

For all the top-level matches the four Jeddah semi-finalists have played this season, none have had the opportunity to compete under the bright lights of the Next Gen ATP Finals title match. That reward — a chance to put the perfect cap on a breakout season — is on the line Friday night.
