The Southampton manager, Ronald Koeman, has warned Morgan Schneiderlin he will have a “big problem” if he refuses to accept the club’s decision to keep him at St Mary’s.

Schneiderlin held talks with Koeman and the Saints chairman, Ralph Krueger, on Friday when it was decided the France midfielder was not “mentally prepared” to play on Saturday in a friendly against Bayer Leverkusen. The 24-year-old has the weekend off and will be given until Monday to come to terms with Southampton’s stance on his future.

“We made the decision about tomorrow’s match together. If this is still the situation next week, then Morgan has a big problem,” Koeman said. “It’s not an easy situation. I was a football player and moved from smaller clubs to bigger clubs.

“But first of all, you have to know you signed a contract and you have to respect your contract.

“We told Morgan to take two days off and think about the situation because we will not change our minds. This is our decision. So we will see on Monday.”

Schneiderlin, who joined the club as an 18-year-old in 2008, has attracted interest from Tottenham and Arsenal this summer. He is understood to be keen on a move to White Hart Lane and a reunion with Mauricio Pochettino, with whom he enjoyed a close relationship at Southampton.

Several Southampton players have been allowed to leave this summer with Rickie Lambert, Adam Lallana, Luke Shaw, Dejan Lovren and Calum Chambers all departing.

“No, it is not unfair [that he has not been allowed to leave like the others]. Unfair is signing a new contract and wanting to go, that’s unfair,” Koeman said. “Not every player is the same and not every situation is the same.”
