Ole Gunnar Solskjaer admitted on Saturday that Manchester United will have to improve significantly on their performance against West Ham if they are to knock Barcelona out of the Champions League. A much-changed United were unconvincing as they beat Manuel Pellegrini's side 2-1 at Old Trafford to maintain their hopes of a Premier League top-four finish thanks to two Paul Pogba penalties, three days before they try to overturn a 1-0 first-leg deficit in their Champions League quarter-final decider at the Camp Nou. "We were lucky it wasn't Barcelona today," said Solskjaer.

"They played better than us but we have one of the best goalkeepers in the world." Felipe Anderson, who had earlier had a goal dubiously disallowed for offside, scored early in the second half to make it 1-1 and Michail Antonio went close twice, hitting the bar and watching in disbelief as David de Gea pulled off a wonder save on his header seconds before Pogba's second spot-kick won the game 10 minutes from time. "That save is unbelievable. He won us the game because at 2-1 down, we would have struggled to create enough," added Solskjaer.
