Arsenal hero Emmanuel Petit believes their title challenge will depend on William Saliba.

Petit says the French youngster is already among the best defenders in the Premier League.

He told Wettbasis: "He's made a huge leap forward this season, he's asserted himself at Arsenal and he's also a key part of the Gunners' successful season. He already seems very mature and very calm in his game.

“After first being on loan (St Etienne, Nice and Marseille) he wanted to show everyone, especially coach Mikel Arteta. He anticipates the opponent's attacks very well, he is technically clean and he is now bursting with self-confidence.

“He's now one of the best defenders in the Premier League, that's for sure. He is the future of Arsenal FC, but also of the French national team."
