Real have suffered badly with injuries in defence this season, with David Alaba and Eder Militao both missing long stretches of the campaign. Saliba has developed into one of the world's best centre-backs and could improve the La Liga giants' defence.
DID YOU KNOW?
Saliba has just two years left on his contract at Arsenal, so this could be their last chance to sell him for a big transfer fee. The Gunners have offered him a contract extension but L'Equipe report that Real are the one club who could lure the Frenchman away from the Emirates.

WHAT NEXT FOR SALIBA?
Saliba will next be in action for Arsenal against PSG in their Champions League semi-final second leg on Wednesday, a tie the Gunners trail 1-0 after the first leg. They then travel to Anfield to play Liverpool in the Premier League.
