Kieron Dyer’s cross-shot from the left was palmed out by Anders Lindegaard and Jamie Mackie found the roof of the net from close range. But three goals in eight minutes saw United roar into the lead.
Jonny Evans headed in the equaliser from close range (64th minute) and four minutes later, Darren Fletcher scoring with a header from Wayne Rooney’s corner. Substitute Javier Hernandez then beat QPR goalkeeper Julio Cesar from Anderson’s pass in the 72nd minute.
