A spokesperson said: "When the matter was brought to the attention of officials at the time it was not possible to identify the person or persons responsible.

"We will continue to try to identify them."

It is now likely police and Chelsea officials will assess closed-circuit TV tapes in a bid to track down the identity of the fan labelled "stupid" by Drogba after the game.

He said: "It's difficult as you see this green light. This is a stupid fan I think.

"The rest of the West Ham fans were good. I think they supported their team. That's what we want to see in the stadium, not these kind of things."

Meanwhile, Chelsea's England midfielder and Saturday's goal hero, Joe Cole, says the victory was a demonstration of the resilience of Avram Grant's team.

Cole struck to score the winner against his former club after Grant told the players they had not been good enough during the first half.

The 26-year-old said: "These are the sort of games that you have to win. We didn't play well, so it's a really important win for us.

"There were a lot of tired legs but we came through in the end, a little bit of quality showed and we got a result.

"A lot has happened at the club this year but we are showing great form at the moment. Not just in terms of the football we are playing but also the fight we showed against West Ham.

"We knew we weren't playing well but we got a result against a side who are going to be top eight, I think.

"It was one of those games where maybe Man United and Arsenal would be looking at us to drop points. So it's such an important result for us."

Cole admitted the game was an aggressive affair with Frank Lampard in particular feeling the effects of a few heavy tackles.

But he added: "It gets a bit aggressive at these games. There were a few players who wanted to get on the right side of the West Ham supporters by getting into Frank Lampard a few times, but it's a London derby and you can expect hard tackles and things like that.

"But we dish out as good as we get and in the end I think it was the right result. The goal meant a lot for Chelsea and I was pleased to score but I would like to have restrained myself some more.

"I still have friends and family who support West Ham, and obviously they're my former club. But all emotions went against us, we weren't playing well and we had a bit of a telling off at half-time. So I was really chuffed to get the points in the end.

"The manager told us we weren't good enough at half-time, that we weren't sharp enough. But we knew it ourselves, we know how well we can play and we found it hard to find second gear in the first-half."
