Ross Barkley is yet to commit his future to Everton
Contract talks between the club and Barkley have not yet produced any results – and the midfielder did not travel to Tanzania for Everton's pre-season tour as he continues his recovery from a groin injury.
Rooney said: "With the ability that Ross has, of course we all want him to be a part of what we're trying to achieve at Everton.
"He can help us get better but the decision about his future is down to him.
"I'm sure he will speak to the manager and do what's right for him."
