Former Manchester United manager Sir Alex Ferguson has revealed in his new autobiography that he doesn't know which Arsenal player left him covered in pizza, although the suspicion is that he may have been Cesc Fabregas.
The incident, later dubbed "Pizzagate", happened after Manchester United's 2-0 victory over the Gunners in October 2004, which brought an end to Arsene Wenger's side's 49-match unbeaten streak in the Premier League.
Ferguson writes that defeat "scrambled Arsène's brain", with the rift between the two managers lasting until the 2009 Champions League semi-final, when Wenger congratulated the Red Devils' manager after his side were beaten.
The pair eventually became acquaintances and some may even say friends, with Ferguson admitting that he felt sorry for Wenger following the 8-2 thrashing of Arsenal at Old Trafford in August 2011.
However, Ferguson still found space to have a couple of sly digs at his old adversary, stating that Jack Wilshere was the only "truly homegrown" player he has produced during his spell with the Gunners.
