Louis van Gaal has admitted that he was angry during Manchester United's draw with Cambridge United in the FA Cup this evening.
The Premier League side created few chances in the first half of their goalless draw with their League Two hosts, leaving them facing a replay at Old Trafford.
The manager told BBC Sport: "Yes of course it is frustrating. We make the same error as against Yeovil Town and against QPR, we did the same playing style more or less in the first half. Then I have to be angry again. In the second half we did much better but OK we are not out of the Cup. That is the most important thing.
"The atmosphere here, the crowd, was fantastic. You know always in advance that all aspects in a game like this is against you. I was angry again but it is part of my job. I want to be very happy at half time.
"I can only give the credit to the coach, to the staff they did marvellous, but what I already said every aspect of the match is against us, the pitch, the referee, everything that you can think about this is against you. Also the fans of course, but that is nice I think."
The draw for the fifth round of the Cup will take place on Monday.
