Should Barkley, who is one of English football's most high profile names, leave Goodison Park, Everton will undoubtedly be looking for a replacement.
Ross Barkley remains undecided on his Everton future and is set to miss Ronald Koeman's deadline to commit himself to Goodison Park.
With the jury out on Ramiro Funes Mori and Jagielka getting older, the Toffees are expected to sign at least one centre-half and have been heavily linked with Burnley's Michael Keane.
"The board has been working a long time to sign Ross for him to stay for a longer period but it is up to the player".
"If you take so much time (in signing) you have doubts (about staying)".
"But we don't wait till August. Young players need experience, they will play in the World Cup and that's good for the development of Jonjoe Kenny, Dominic Calvert-Lewin and Ademola Lookman". "We have already tried to get players in for next season in the front positions".
Conservatives open up record lead - ICM poll
The Conservatives finished as the largest party on six councils, and were joint largest alongside the SNP in Stirling. And now the Tories have older people in their sights too - as they gear up to end the pensions triple lock.
"It is up to the player and he needs to make a decision".
Everton have just two matches remaining in their season and Koeman feels the time has come for Barkley to make up his mind.
Ronald Koeman's Everton suffered back-to-back Premier League defeats for the first time this season after going down 1-0 at Swansea on Saturday.
And when you consider that he has struggled to nail down a spot in the England team, or even squad, since Euro 2016, you sense that a fresh start may be in order for the midfielder.
He has struck up a good understanding with Premier League top scorer Romelu Lukaku, and his performances in 2017 in particular have caught the attention of north London rivals Arsenal and Tottenham, with the latter touted as the favourites to land him this summer.
