Matteo Berrettini is one of the most underrated forces in tennis today and has enough talent to 'break the world,' says Ivan Ljubicic.
The Italian is part of the LJ Sports Group, a sports management company that Ljubicic, who is Roger Federer's coach, runs.
Berrettini is currently a top ten player, has reached the ATP Finals before, and won the Serbian Open last week, although he is sometimes overlooked within Italian tennis due to the richly talented teenage duo Jannik Sinner and Lorenzo Musetti.
Ljubicic, though, has warned that we still haven't seen the best of Berrettini, and that once he masters his physical conditioning he will be a true force on the ATP Tour.
Asked by Gazzetta dello Sport if Berrettini is underestimated, Ljubicic said: "It's true, and it happens above all in Italy where someone continues to think that he is a top ten player by chance.
"Forgetting where he started from, what tournaments he played in early 2019 and where he found himself at the end of that year.
"You do not qualify for the ATP Finals by divine grace. Ask any player of the past and present what technical value it has to get the pass for that tournament.
"Matteo just has to feel good physically, for the rest he has a top player game and is only 25 years old. It means that at least for the next five years he will break the world. Only he will know his limits.
"He was just angry that he had started the season well in Australia and the abdominal injury stopped him at a very brilliant moment."
