A Birmingham fan gestures at Villa's Peter Enckleman (MatthewAshton/Empics)

Dozens of fans ran onto the playing area after each of Blues' goals with one supporter goading Villa goalkeeper Peter Enckelman after he conceded a bizarre own goal following Olof Mellberg`s throw-in.

A statement from FA said: 'Further to last night's Birmingham City v Aston Villa Premier League match, we can confirm that the FA is today contacting Birmingham City to request their views on certain issues involving supporters encroaching on to the pitch.

'We are also awaiting reports from the match officials and an FA crowd safety observer.'

However, Birmingham chairman David Gold believes 'little exceptions' should be made for his club.

He played down the scenes, attributing them to high spirits associated with the highly-anticipated derby game.

'We must make little exceptions to the rules,' he told BBC Radio Five Live.

'This is Birmingham City in the Premier League for the first time in 16 years.'

The chairman also denied that any of the incidents had been serious, refusing even to class them as pitch invasions.

'We have to be careful we don't overreact,' he added on Sky Sports News.

'I am really sorry that we are focussing on that one stupid young man who came onto the pitch (to confront Enckelman) and disgraced himself and disgraced Birmingham and spoilt it for 30,000 perfectly-behaved fans.

'We will track him down and he will be banned for life.

'A few dozen fans came on the pitch at a moment of great excitement - Birmingham and Villa haven't played each other in a serious competition for 16 years.

'It was a handful of fans in pure jubilation. This was not an invasion where fans were fighting each other or were attacking players.'

Gold added that he believed security at St Andrews was the best it could have been and he did not wish to see a return to perimeter fencing.

'In all the great matches you are, from time to time, going to get some fans on the pitch - that is part of football.

'If you had more security than you had fans, you would still get people coming on the pitch.

'I believe our security is the very best. To expect more you are going to return to caging the fans back in and that is inappropriate.

'It was not an invasion but that does not mean we are not treating it seriously and we will ensure it is kept to a minimum.

'But we should not dwell too long on that issue.'
