Louis van Gaal says Manchester United's form does not worry him despite another goalless draw this week against PSV.

United needed a win to guarantee their place in the Champions League knockouts but failed to break down Phillip Cocu's side at Old Trafford on Wednesday.

A number of fans made their feelings clear as United meandered to a fourth scoreless draw in seven outings, but Van Gaal says he will not become concerned until his side stop creating opportunities against defensive teams.

"If we weren't creating chances I'd be worried, but we are and we don't give too much away - normally our results are good," he said on Friday ahead of the meeting with Leicester City.

"The fans have to be happy, you are playing for the fans but you have to see how our opponents are playing against us.

"Our defensive organisation is normally the best part of our game. We've proved that more than ever this season."
