Tottenham boss Andre Villas-Boas feels Wayne Rooney is even more dangerous now in the shadow of Manchester United teammate Robin van Persie.
The Dutchman has scored 21 goals in a sensational debut season and stolen the limelight from his strike partner Rooney.
AVB said: "We're always very unlucky as Rooney seems to return just in time for our games. He's had the midweek win over West Ham to get back to form and I think he is the man who makes Manchester United tick.
"We have to concentrate on what's realistic now and that's to get closer to Chelsea."
