The England striker was left on the bench for tonight's unlucky Champions League loss to Real Madrid at Old Trafford and Keane feels it could be time for Rooney to assess his options.
"It surprised us all that [Sir Alex] left Wayne Rooney out. Maybe the writing is on the wall for him," he said on ITV.
"Wayne needs a game or two, to be honest. He did okay in the second half against Norwich but he needs a game."
