West Ham United boss Sam Allardyce admitted his side's first-half performance was not good enough in their 3-1 defeat at Manchester United.

Goals from Danny Wellbeck, Adnan Januzaj and Ashley Young sent them to defeat although Carlton Cole netted a late consolation.

Allardyce told the club website: "I can't complain about Saturday's result and I can't complain about the fact that we were 2-0 down at half-time because of our own deficiencies in our performance.

"Manchester United's players will take full advantage of basic mistakes in your own half, which they did on the two goals.

"You always have to weather the storm when you start at Old Trafford, not giving too much encouragement. I think unfortunately for us we weren't able to do that and ended up fighting a losing battle in the second half.

"It's always a tough task from there on and my disappointment was that our first half was not good enough."
