Liverpool (AFP) - Everton manager Ronald Koeman has warned midfielder Ross Barkley that he will be sold if he refuses to sign a new contract.
The England international's current deal runs out at the end of next season, with no new agreement yet in place.
Manchester United, Manchester City, Tottenham, Chelsea and Arsenal have all been linked with a possible move for Barkley in recent months.
The 23-year-old, a boyhood Everton fan, graduated from the academy at Goodison Park, but his future at the club looks increasingly uncertain.
Barkley produced an outstanding performance as Everton beat Leicester 4-2 in the Premier League on Sunday.
However, Koeman suggested after the game that he would not allow the midfielder's future to remain unresolved beyond the summer.
Asked how he would resolve the contract stand-off, Koeman said: "We offer him a new contract and two possibilities, one is sign that contract, if he doesn't, we need to sell the player. It is simple. It is not so difficult in my opinion."
Barkley combined superbly with Romelu Lukaku, who scored twice to take his Premier League goals total for the season to 23.
Lukaku's future at Everton is also uncertain, with the Belgium striker having recently rejected an offer to extend his contract beyond 2019.
Koeman wants to keep both players, but not at any price.
The manager said: "Even if they don't perform on the level, we try to keep the best players.
"We spoke a lot about Ross and Rom because they are really important, most of the time the quality of the players can be the difference between Everton and the opponent.
"Today they played really well. We know Rom is a great finisher but Ross played really well between the lines.
"I think he should have scored one, but it is what you want to see they played outstanding. The whole team performance was outstanding."
