Chelsea have vowed to ban for life the supporters who threw coins at Manchester City's players as they celebrated their goal in a 5-1 FA Cup fifth round drubbing at Stamford Bridge.

The ugly scenes came just 24 hours after West Brom's Chris Brunt was struck by a 50p piece hurled by one of his own supporters in their FA Cup defeat by Reading.

Referee Andre Marriner picked up three coins thrown at City's players — largely made up of teenagers after boss Manuel Pellegrini decided to play a near-reserve team — when they were huddled together celebrating David Faupala's debut goal in the first half.

'I was aware,' Chelsea manager Hiddink admitted. 'I like always to face the facts. There were coins thrown to the Man City players when they celebrated. We condemn it and I condemn it strongly. I think Chelsea will react. Those people they must not come into stadiums.'

A Chelsea spokesman also said: 'We condemn such idiotic and dangerous behaviour. If we can identify those responsible then we will ban them from Stamford Bridge.

'It's worth noting it's a criminal offence, too, and we will support any police prosecution if we can identify along with the police those individuals responsible for that behaviour.'

City manager Manuel Pellegrini denied seeing the incident and had not spoken to his players about it in the dressing room.

A man was arrested on Sunday night after allegedly throwing a lighter on to the pitch at Stamford Bridge during the game.

'The man was arrested for throwing a lighter onto the pitch and he currently remains in custody pending further enquires,' police said in a statement.

'Officers continue to carry out enquires into incidents of coin throwing.'

On Saturday, West Brom's Brunt was cut beneath the eye when he walked over to give his shirt to their travelling supporters following their 3-1 defeat to Reading.

The 31-year-old has demanded that the thug who chucked the coin turn themselves into the police.

Thames Valley police are investigating the incident as assault and West Brom will also issue a life ban to the guilty person.
