LOUIS VAN GAAL was disappointed to see his Manchester United side concede goals due to individual mistakes in a stunning 4-0 defeat to MK Dons - but defended his decision to make 10 changes from the team that drew 1-1 with Sunderland on Saturday.

Jonny Evans made a glaring howler for the opener against the League One side in the Capital One Cup as the Dutchman's side were left still looking for a first competitive win under him.

"You have to analyse the problem and then you have to take your matches and I have done that and I think the changes were good," he said

"But it's also risky to change and to play one against one and therefore Milton Keynes could score.

"You don't have to forget that we have nine injuries and we have a very young team. I have seen them trying to do their utmost best.

"So you cannot expect more of players.

"We were also unlucky because they scored out of our errors at once and then you are always behind."

After a promising pre-season, the wheels appear to be coming off United's campaign already but Van Gaal wants the fans to stick by his team and his playing beliefs.

"They have to believe in our philosophy," he said.

"We are building up a team and you cannot make it in one month, not in one year. Of course it's very disappointing but I hope they shall maintain their confidence in the club and in our philosophy because that philosophy takes time."

MK Dons boss Karl Robinson said: "I'm a little bit shocked to be walking off and seeing the scoreline.

"It's ridiculous, it's something that dreams are made of for these players.

"We work hard here and you've seen a youthful energy in the team."

He went on: "I think my players deserve an awful lot of credit tonight. The football club does and Milton Keynes does.

"This is a game for Milton Keynes as a city."
