Patrick Mouratoglou believes that
Matteo Berrettini is the top ATP pro with the biggest weakness, his backhand.
Matteo Berrettini is a fabulous tennis player yet there is something that is holding him back quite a bit - his backhand. The backhand is not a very good shot for Berrettini who struggles with it quite a bit. When he plays on surfaces that allow him to dictate the play such as fast hard courts and grass courts he can be dangerous but sometimes his backhand simply lets him down.
Patrick Mouratoglou agrees with that which is why he ranks him a level below the likes of Medvedev, Zverev and Tsitsipas. Speaking about the Italian, he praised him for his competitive spirit:
“First, Matteo Berrettini is an incredible fighter and competitor. He refuses to lose. Watching [him play] I think ‘wow, tennis-wise there are guys who play the same [level] but they don’t have that. If you look at the top guys, they all have that. Zverev, Medvedev, Tsitsipas, Berrettini, they refuse to lose."
Turning his attention further in depth towards Berrettini he explained his biggest weakness:
“But, we also have to say that he’s the only top guy who has a huge weakness. His backhand is very weak. In the big matches against the best players it’s a big disadvantage. He plays smart, [playing his backhand] to get a forehand on the next shot."
Mouratoglou further said:
“And he has mastered the slice backhand. I put him in the same group as Medvedev, Zverev and Tsitsipas,
because he is very consistent at the highest level, because of his
ranking, and because he is a Grand Slam finalist. On the other hand, for me he is a bit under them because he has a big weakness.”
