Manchester United manager Louis van Gaal has claimed that the supporters are "right" to boo the team following their 1-0 defeat to Southampton at Old Trafford on Saturday.

The Red Devils could only muster one shot on target and were eventually undone in the 87th minute by new Southampton striker Charlie Austin, who scored less than 10 minutes after making his debut as a substitute.

Boos could be heard around Old Trafford, but Van Gaal has called on the whole club to "stick together".

"I wanted to win this game and that's why I changed Cameron Borthwick-Jackson for Adnan Januzaj - that is a risk you take," BBC Sport quotes Van Gaal as saying.

"It was a poor game and we didn't create so much and neither did our opponent. Because you have to meet expectation and expectations are very high, that gives a lot of pressure for the players.

"[The fans] are right [to boo], I cannot deny that. I have seen the match also. In better or for worse we have to stick together. We are working very hard but we have a lot of injuries that you cannot change."

United remain fifth in the Premier League table, five points adrift of a Champions League place.
