Manchester United manager Jose Mourinho has claimed that two "unbelieveable" goals cost his side during their 2-1 defeat to local rivals Manchester City in this afternoon's derby at Old Trafford.

City controlled the ball for the vast majority of the contest, but for all of their possession it was close-range finishes from David Silva and Nicolas Otamendi which handed them all three points after United had failed to clear their lines from set pieces.

Mourinho was also left unhappy with referee Michael Oliver after seeing Ander Herrera's penalty claim turned down late on as United slipped 11 points adrift of the league leaders.

"Like last season, we had a penalty with City - Bravo on Rooney. This season is the same. But Michael was unlucky as it was a clear penalty. Two bad goals. Not what you expect to concede. City have good qualities. They have a huge percentage of ball but their creation we kept control of," he told BBC Sport.

"We did enough to win the game? It depends on your perspective. They had more of the ball and apparently more control because they kept the ball more than us. But I think the players fought enough. Without any analysing the match is made of incidents and the penalty was a big incident. The referee is a human being and he tried his best. He was very committed to have a good match which I think he had but made one mistake which was a crucial mistake.

"They scored two goals which were quite unbelievable to concede. They scored two goals out of nothing with rebounds....two easy goals. We did good things, we did bad things. I think they are a very good team, they are lucky, they have decisions in their favour. I'm pretty sure everyone is going to fight for points and try and reduce the distance, but the advantage is a very good one."

The victory also sees City set a new single-season record of 14 Premier League wins in a row, the last four of which have all been by a 2-1 scoreline.
