After Manchester United ended Arsenal’s 49 game unbeaten run at Old Trafford there was an altercation in the tunnel at the end of the game involving a piece of pizza being thrown at United boss Sir Alex Ferguson.
The Scot in his latest autobiography explains the background to the incident and who the culprit might be.
"My recollection of that fabled incident is that when Ruud van Nistelrooy came into the dressing room, he complained that Arsene Wenger had been giving him stick as he left the pitch. Right away I rushed out to say to Arsene: 'You leave my players alone.' He was incensed at losing the game. That was the reason for his combative behaviour.
"The next thing I knew I had pizza all over me. They say it was Cesc Fabregas who threw the pizza at me but, to this day, I have no idea who the culprit was.
"That day created a division between us. The wound was not fully healed until the Champions League semi-final in 2009, when Arsene invited us into his room after the game and congratulated us."
