Andy Murray is a "gladiator" and his love for tennis means he could yet prolong his career, according to former world number eight Diego Schwartzman.

Murray has endured a difficult few years with injuries, undergoing surgery on both hips in 2018 and 2019.

The three-time major champion has repeatedly said he is approaching the end of his career, revealing in February that he does not "plan on playing much past this summer".

Murray is currently preparing for what will likely be his final appearance at the French Open, having sat out five of the last six tournaments at Roland-Garros.

Schwartzman, however, feels Murray's love for the game could lead to him playing on for longer than anticipated.  

"His life is tennis and I think he enjoys it. I think this is his legacy," Schwartzman – who won his only tour-level meeting with Murray in Antwerp in 2021 – told Stats Perform.

"No matter what you do, your age or how you are doing, if you really love the sport and you love what you do, you can do it and you can push hard for as many years and as many tournaments as you want.

"He's a fighter, a gladiator, and he's been doing the same since he was very young, and for us also, sharing tournaments and sharing moments, he has the passion out there. 

"So, it's good to see these kinds of guys because tennis always needs guys who love the sport, and this is the one for sure."

Murray would surely have added to his one US Open title and two Wimbledon crowns if not for the presence of the 'big three' of Novak Djokovic, Rafael Nadal and Roger Federer. The Scot has lost five grand slam finals to Djokovic and one to Federer. 

Schwartzman says the importance of preparation is the main thing he learned from being on tour with those three greats, though he refused to say who was the greatest of all time. 

"I know them very well, playing them on court, outside of the court," the Argentine added. "The good thing for me and many guys who share the tournaments with them is how differently they prepare the tournaments.

"How differently they do things with food, with practice, with everything. It's crazy.

"I think, okay, 'in one small way he's the best to do this side of the game', and then the other one is the best [at another aspect], so it's not my thing, who the GOAT is."
