The Football Association have requested television footage of the clash between Arsenal players towards the end of last night's Carling Cup semi-final second leg at White Hart Lane, after referee Howard Webb confirmed he had not seen the entire incident.Tottenham booked a place at Wembley with a resounding 5-1 win over their arch rivals. During the closing stages, with the tie already lost, Nicklas Bendtner - who had earlier scored an own goal - became involved in an altercation with team-mate Emmanuel Adebayor, and appeared to complain of being headbutted by the Togo international. Arsenal captain William Gallas stepped in to try to calm matters down, before then himself being confronted by the angry young Danish striker. Eventually, referee Webb had to intervene to restore order. As the Yorkshire official revealed he did not witness the events in their entirety, the FA have now asked broadcasters to provide any relevant television footage. Once that is obtained, any incidents will be shown to Webb for his opinion. Should the referee indicate action would have been taken on the night had he witnessed it first hand, such as a red card for violent conduct, the FA can then retrospectively issue charges against any individuals. While still photographs in today's press clearly show the Arsenal players involved in some sort of confrontation, it is understood there may not be any footage of the actual alleged headbutt itself. Adebayor has apologised for his part in the bust-up. 'I think that we should have been more calm during the game and although I was pleased to get a goal back for the team when I came on, I am sorry for the disagreement with my team-mate Nicklas,' Adebayor said on the club's official website. 'We are both passionate about this club and sometimes that can be projected in the wrong way. 'It was a mistake. We want to focus on the games ahead and rely on our squad's great togetherness to achieve a fantastic season.' The 23-year-old has been in fine form for the Gunners, with his goal on Tuesday night when coming off the bench a 16th of the campaign. Adebayor firmly believes the events at White Hart Lane will not unsettle Arsene Wenger's squad, which remains very much in the hunt for honours. The Togo striker said: 'We are a strong unit and what happened last night against Spurs will strengthen our desire and determination to compete for other targets.' Arsenal manager Arsene Wenger maintained he was not aware of the incident, while captain Gallas refused to single out anyone for blame. The France defender said: 'I don't know what happened. I think everybody was disappointed with the score and they were nervous. 'They know they made a mistake. Maybe they will speak with the boss to see why they did that.' Gallas added: 'All the young boys wanted to go to Wembley and I know it is difficult to accept. The fans are upset and we are upset. All the club are upset - and we have to accept it. 'Now we have to be strong and forget everything because on Saturday we have another big game which will not be easy.' Gallas declared: 'We have to forget this game and we have to be focused. 'We have to be strong because Newcastle have a new manager and they want a result at the Emirates Stadium. 'For us we have to win that game because we have some ambition.'
