London - Tottenham Hotspur had won on their previous two visits to Old Trafford but were effectively knocked out of the game by the 34th minute after goals from Marouane Fellaini, Michael Carrick and Wayne Rooney, who scored for the 19th time this season.
WATCH: Rooney knocked out in home boxing "match"
Rooney's goal celebration poked fun at the pre-match hype regarding a video of the striker boxing against former Red Devil defender Phil Bardsley.
After the match, the Manchester United captain insisted the latest headlines about his private life had not affected his performance.
"That's the world we live in today." remarked Rooney.
"It's in my own home, it's not public, it's what friends do - they mess around in the house.
"It was a couple of mates in a private house, and somehow it's managed to get on the front page of a national newspaper.
"I've just been focused on the game, it's more interesting for other people rather than for me. You've seen today, I've done a professional job and helped my team win 3-0."
Following the win against Spurs, Manchester United remain in fourth place but are now just two points behind second-placed Manchester City.
On Sunday, Rooney will lead his side out at Anfield against Liverpool in a mouth-watering English Premiership encounter.
