Manchester United boss Louis van Gaal has admitted that some of his players were nervous in their opening match of the 2014-15 Premier League season.

United went down 2-1 to Swansea City at Old Trafford earlier this afternoon as the Dutchman's first league game in charge of the former English champions ended in disappointment.

"I saw a lot of players very nervous, making the wrong choices. These players have to cope. It's Manchester United," he told reporters at a press conference.

United, who finished seventh last season – a position that cost former boss David Moyes his job, return to action against Sunderland next weekend.
