Cristiano Ronaldo continued his astonishing scoring spree to steer Manchester United through to the fifth round of the FA Cup with a 3-1 win over Tottenham.
The Portugal winger set a seasonal best tally of 25 goals for the club with a brace against 10-man Spurs.
Yet the Carling Cup finalists will be left cursing their luck after squandering a number of chances.
They were also left to rue defender Michael Dawson's sending off at a crucial stage of the game.
Tottenham went ahead in the 24th minute when Aaron Lennon skipped away from Patrice Evra.
He delivered the ball into the area and Robbie Keane scored from close range.
But United stepped up the pace and Radek Cerny did well to tip over a shot from Ryan Giggs after 37 minutes.
The equaliser came a minute later and Giggs played a crucial role in the build up.
He held off the challenge of Young-Pyo Lee and that enabled Carlos Tevez to fire a shot into the corner beyond Cerny.
Jermaine Jenas should have regained the lead for Spurs in stoppage time when he was clean through.
However, he failed to get enough power on his effort and Edwin van der Sar was able to push it to safety.
The tie took a dramatic turn in the 68th minute when Dawson was sent off for a handball in the area under pressure from Wayne Rooney.
Ronaldo stepped and slotted the spot kick into the corner to put United 2-1 ahead with his 24th goal for the club.
Down to 10 men and a goal down, Tottenham looked a little bit deflated as the game entered a crucial stage.
Ronaldo got his second in the 88th minute when he got away from substitute Chris Gunter and his shot squirmed under Cerny's body, leaving the goalkeeper red-faced.
