The Manchester United and England captain has been struggling for form this season and has not started a league game since September 24.
He has been linked with a move away from Old Trafford as he tries to resurrect his career.
And on being asked about speculation linking Rooney with a return to Everton, Ronald Koeman said “He is a great player and he still hasn’t finished his career. I don’t know his situation, I need to respect that. If there is a possibility of Rooney at Everton, I would be very pleased.”
