Manchester United manager Louis van Gaal was unable to hide his frustration following the scoreless draw at Cambridge in the FA Cup fourth round.

The Red Devils had Angel di Maria, Radamel Falcao, Marcos Rojo and Daley Blind in their side but were unable to break down their League Two opponents.

The hosts deservedly claimed a replay at Old Trafford and the United boss found fault with the pitch, the referee and his players afterwards.

“Every aspect of a match is against us,” Van Gaal said. “We have to come here, the pitch is not so good, but that can influence also that you play in another playing style.

“The opponents are always giving a lot more than normal.”

Van Gaal also took a swipe at the performance of match referee Chris Foy before moving on to the lack of ideas and invention from his team of international stars.

“We made the same error as against Yeovil Town and against QPR, that we played in the same playing style as the opponent and that we don’t have to do,” he added.

United are back on league duty next weekend with a home game against struggling Leicester City. The Red Devils are installed as 1.30 favourites for the win with Nigel Pearson’s team at 9.04 and the draw at 5.06.

Despite his criticism of the overall performance on the night, van Gaal was able to take solace in the fact United had not become the victims of a cup giant-killing act.

“We are still in the cup and that’s the most important thing. I’ve seen lots of times big clubs losing against such opponents.”
