Ander Herrera has conceded that Manchester United did not play well during their 1-0 win over Watford this evening.
The visiting Hornets created a number of chances at Old Trafford, but they were unable to find a way past David de Gea in the home goal.
Then, the three points were sealed seven minutes from time by Herrera's fellow Spaniard Juan Mata.
"We didn't play so good, but we have to learn to win these games. There was a lot of wind in the stadium and the pitch was dry. We couldn't move the ball, that is our style," he told MUTV.
"We were not so good with the ball and we gave them some chances. But if we want to fight for everything and the top four we have to win these games."
The victory has drawn the Red Devils level on points with fourth-placed rivals Manchester City.
