Ronald Koeman has warned Ross Barkley that he must improve ‘in all aspects’ following his half-time hooking in Everton’s win over Sunderland.
The England international was withdrawn during the interval at the Stadium of Light on Monday after a disappointing 45 minutes for the Blues.
Koeman held face-to-face talks with Barkley earlier this week to explain his decision and has urged the 22-year-old to bounce back from the setback.
He said: “There was a reason to change Ross at half-time because he did not play well.
“He lost many balls and players of that quality can’t lose those kinds of balls. We analysed the game as always and had individual talks.
“I had them with Ross and he needs to improve and, OK, we will see at the weekend.”
Barkley’s substitution became the latest setback in his current prospects after failing to feature for England at Euro 2016 and being subsequently overlooked by Sam Allardyce.
“That is the past, in my opinion, what counts is what happens now. You get game time for your national team because you play at a good level for your club,” added Koeman.
“It was one game what happened last Monday and he understands. I showed him the clips and there is no escape. Ross needs to be the key player between defenders and strikers.
“You look at his qualities and his position is to create. In all aspects he needs to improve but he is still a young player, no question.”
