Arsenal wants to keep Saliba by offering him a new long-term deal, but he may be open to leaving if Real Madrid makes him an attractive offer.
Real Madrid is preparing for the departure of two of their current defenders, Antonio Rudiger and David Alaba, who are expected to leave the team next summer.
The Spanish club sees Saliba as a potential partner for their new signing, Dean Huijsen, who recently joined from Bournemouth in the Premier League.
Saliba's representatives have requested a meeting with Arsenal's management team to discuss his future at the club.
