Juan Mata: Man United must learn from Arsenal defeat

“Before the game our goal was to keep the top spot of the Premiership, but it wasn’t our day as we saw from the kick-off.“

Midfielder Juan Mata accepts Manchester United must learn the harsh lessons of their horrible start in the 3-0 defeat at Arsenal, but also not forget what took them to the top of the Barclays Premier League table.

Louis van Gaal was left stunned by the manner of the loss at the Emirates Stadium on Sunday, where the Gunners had put the contest beyond his side with three goals inside the opening 20 minutes – the first two coming within 74 seconds of each other.
