United manager Louis van Gaal said: "The images shall tell everything. The police was also taping. It's a lot of emotion for the people, but for us it's the second time in London that we have to start later." The experienced Dutchman said it was not the first time he had seen a team bus being attacked.
"It's not so nice, but it's part of the job I have to say" said Van Gaal, whose team needed a victory in today's match to have a realistic chance of qualifying for the Champions League next season. They lost 3-2.
Aware of the possible impact of the trouble on his team before such a key game, he added: "The way we have been received is not the proper way, of course. That makes all the influence on the players and that is a pity."
However, West Ham co-owner David Sullivan said that United was to blame for not arriving earlier for such a high-profile game. "I'm gravely disappointed, more for our supporters. What people forget is they've got trains and buses to get home and we've got a wonderful, wonderful show after the game for them. Many just can't stay any more.
"Man United should have got here at 4pm. They know it's our last game. They had the same problem at Tottenham a few weeks ago." About 15 minutes before the delayed kick-off, hundreds of West Ham fans were still outside the stadium, having mostly congregated around a 1966 World Cup sculpture featuring West Ham and England stars Bobby Moore, Geoff Hurst and Martin Peters.
Around 100 police in riot gear stood around in formation and watched, with at least half a dozen officers on horseback. The street was littered with smashed bottles.
