Ander Herrera has played down the significance of Manchester United's 7-0 thrashing of Los Angeles Galaxy and believes that there is plenty of room for improvement.

United marked the beginning of the Louis van Gaal era in style by thumping the MLS outfit by seven goals to kick off their pre-season campaign with a bang.

"Let's not forget this is a friendly and we still have many things to improve on," he told the club's official channel.

"We are happy with the result but our coach [Van Gaal] is a very demanding coach. He won't let us sit back and relax. He always looks for perfection and for that reason he is ideal for a club that always looks to achieve the greatest things."

The Red Devils face sterner tests with Real Madrid, Roma and Inter Milan in the United States this summer.
