Manchester United manager Louis van Gaal says his side must learn to be more clinical after today's goalless draw at Tottenham.

The Reds had the better of the first half but failed to find the net at White Hart Lane.

But speaking after the game, Van Gaal also felt playing twice in 48 hours affected the game's quality.

"You can create six to eight chances but you have to finish them. But you could also see the difference in the second half. There was no football anymore. It was a struggle for life," said Van Gaal.
