The Tottenham striker failed to have an impact as his side went down 3-0 at home.
Speaking on Sky Sports, Keane said: "He scored against Poland – they're no mugs. But for the closing down, he's your top man.
"Knock someone open, shout at people! I never see him digging anyone out. There's a bit of a hangover from the summer that would be my concern.
"Sprint at people, get hold of the ball! At 2-0 down, he tried this Roy of the Rovers move. It was never going to work."
