Ross Barkley is doing everything in his power to fulfil his potential according to Everton boss Ronald Koeman.

"He's been positive, really positive," said Koeman.

"The most important thing in this situation is the player really knows himself it's a big season for him to show he is not any more that (emerging) talent.

"He knows about that pressure because he's a local boy, that always gives more pressure. But I think he can handle that pressure and deal with it.

"That's a responsibility for the player more than maybe it was the last two years. He's working hard trying to improve and I think there's still a lot of space to improve to be finally a very good player."

Koeman does not feel Barkley's frustrations with England selection should be the driving force behind his efforts.

"Sometimes you get outside inspiration but I think that mentality needs to come out of yourself, not that maybe he was disappointed with what happened in the summer," he said.

"No. Start every day by doing your job, be professional. Of course you need help and the confidence of the coach, that kind of stuff, but it always starts with the player by himself."
