David de Gea: Man United’s goalkeeper needs scan on knee injury

And Van Gaal said: “I think it’s the law of Murphy”.

Van Gaal agreed that United’s defence had not coped well with Midtjylland’s giant 6ft 7in striker Paul Onuachu, who scored the second goal, although he did point out that their first had been deflected past Romero.

Louis van Gaal’s miserable tenure at Manchester United plumbed new depths on Thursday night, as the manager agreed with expletive-laden chants from furious fans about his side’s performance.

De Gea joined Wayne Rooney, another crucial clog in the United system on the injured list and this does not bode well for Louis van Gaal who is trying to ensure that United somehow make it back to the Champions League next season.

Muhren has become the latest former Red Devils star to criticise the embattled United boss and says he has already had enough time to turn the club’s fortunes around.

Sean Bones, vice-chairman of the Manchester United Supporters’ Trust, said: “I have never heard our supporters sing songs like that, in all the games I have been to”.

United take on League One opponents Shrewsbury Town in an FA Cup fixture on Monday.

“I’ve watched them play a number of times and it’s not been an easy season for Van Gaal and the team”. We have to pick ourselves up and go again, there is no other way.

“I think the players need to take a lot of responsibility for the performance and show some pride when they wear the United shirt”.

“It is the Law of Murphy”, said Van Gaal.

Add FC Midtjylland – a team formed as recently as 1999 and with 8,000 followers on Twitter compared to United’s 7 million – to the list of so-called minnows to have conquered United this season.

However, yet another defeat has led to more calls for his sacking from fans and pundits alike and Thorup conceded a result like this one will raise question marks about the manager’s future. “I think we caused a lot of our own problems”. “The performance is nowhere near good enough and it has to be better”. After lunch we’ll go to San Siro, bringing the Interista spirit with us, hoping to see Inter win.

Just days after United were embarrassed in a 2-1 defeat at Premier League strugglers Sunderland, this was another chastening experience for van Gaal, whose miserable reign hit a new low in the unglamourous surroundings of the MCH Arena.
