Louis van Gaal has spoken of his frustration over Manchester United’s failure to score goals in the past three games.

Of course it is a concern. I said that after the match against Middlesbrough, when we created a lot of chances. You have to finish the chances. In the last minute of the first half, Ander Herrera could have finished it but he didn’t. I asked him and he didn’t know why, so that is a pity. But I can’t complain about the result because I don’t think we were the better team today.

I am not happy because if you want to be the champions, you have to win these kinds of matches. Arsenal beat Swansea, for example. We lost against Swansea, even though we were the better team, but they have beaten them 3-0.
