Dimitar Berbatov struck a hat-trick to cement Manchester United’s lead at the top of the Premier League as Darren Bent scored on his Aston Villa debut to derail Manchester City’s title push. Berbatov took his goals tally for the season to 18 in all competitions as Birmingham were crushed 5-0 at Old Trafford, evergreen midfielder Ryan Giggs and Nani scoring the other goals for the Red Devils. “Dimitar was marvellous,” United manager Sir Alex Ferguson said quoted by fifa.com. “He could have scored more and we were a bit wasteful at times with our finishing but you can’t complain at that performance, that was the important thing.” In the late kick-off, Villa’s £24m signing Bent struck on 18 minutes against City to give Gerard Houllier’s side a precious 1-0 win. Bent, a surprise departure from Sunderland, has now scored on his debut for three clubs, having struck goals in his first games for Charlton, Sunderland, and now Villa. The defeat was a blow to big-spending City, who could have gone level on points with United at the top of the table with a win.
