Arsenal legend Tony Adams has admitted that he has some concerns about William Saliba ahead of his former club's top-of-the-table clash with Manchester City on Wednesday night.
Saliba has been a revelation for Arsenal this season after returning from a loan spell at Marseille, quickly establishing himself as a key player in Mikel Arteta's starting XI.
His performances have seen the Gunners move to the top of the table, but they have picked up just one point from their last two games and looked susceptible from set-pieces.
Adams feels Saliba has some issues with the physical side of the game, and was particularly worried by what he saw from the Frenchman when he went up against Ivan Toney in Arsenal's 1-1 draw with Brentford on Saturday.
