Everton manager Ronald Koeman has said he is not confident that Ross Barkley will stay but is "not worried" about the situation.
Everton are primed to spend heavily in the summer in order to compete both domestically and overseas next season, and they will be loath to lose Barkley to Tottenham, a team they want to close the gap on rather than help strengthen.
Lukaku has hit 24 Premier League goals in the most prolific campaign of his career, with the 24-year-old regularly linked with a return to former club Chelsea.
The manager said at the time: "Either he accepts the contract or we sell the player".
No (I'm not confident it will be sorted) because it's a long time that he is thinking about his future.
The 23-year-old Barkley is arguably one of the most talented midfielders in the Premier League and is looking increasingly likely to leave current club Everton having yet to sign a new contract with just a year remaining on his current deal.
The Dutch coach was non-committal on that, but when asked if Barkley would be part of his plans in pre-season if the impasse was not resolved he replied: "I don't know".
"I am not anxious because I like to work with players who want to stay". If there is interest in him then the board will know and they will come to the club if they have interest in the player.
"I think it's going to be tougher for him at Everton than he thought". We are looking for players in that position. We will go on.
The academy produced attacking midfielder has been offered a new contract at Goodison Park but is yet to sign it.
"Time for him to decide", he said on May 11. Next weekend we need an answer.
