Stephane Sessegnon, Morgan Amalfitano and Saido Berahino performed brilliantly as West Brom deservedly beat Manchester United.
There was nothing in the first half to hint of the excitement to follow. There were chances for Javier Hernandez from two excellent Luis Nani crosses, Anderson headed over a Shinji Kagawa cross, and Berahino glanced an Amalfitano cross a couple of yards wide. Then, just before half time, Sessegnon skied a Claudio Yacob flick-on.
The second half was marked by a drastic improvement from West Brom and a woeful drop-off from United, just as David Moyes inexplicably replaced Kagawa with Adnan Januzaj, who would go on to put in a dreadful performance reminiscent of Old Trafford antihero Bebe.
On the 54th minute, Amalfitano scored a superb solo goal, cutting in from the right, nutmegging Rio Ferdinand, and leaving David De Gea prostrate as the winger arrogantly chipped him.
United hit back almost instantly, when Wayne Rooney’s cross from the left hand side almost found Javier Hernandez’s diving header, but found its way past Myhill at the back post to equalise.
The scores were level for just ten minutes, as Berahino scored a wonderful goal. Sessegnon clipped a pass forward to Amalfitano, whose lay-off allowed Berahino to blast a left-footed shot from 20 yards past a static De Gea. West Brom thoroughly deserved their first Old Trafford victory in 35 years.
