West Ham United have said that they would issue life-time bans to unruly fans after Manchester United's team bus was attacked by supporters before kick-off.

Tuesday's 3-2 win in the Premier League was overshadowed by West Ham fans pelting United's coach with bottles on their arrival to the ground.

The Hammers are now working with police to identify those involved.

"It was an extraordinary night full of extraordinary moments in front of extraordinary fans. 99 per cent of whom behaved impeccably and were a credit to the club," a statement read.

"We have already had thousands of tweets and emails from fans to say how proud they were to be a part of such a special evening in West Ham's history.

"However, we are aware that there were some supporters outside the Boleyn Ground who didn't act in an appropriate way when the Manchester United team bus was damaged.

"That was not acceptable and we will work with the police to identify those responsible and ban them for life."
