Arsenal manager Arsene Wenger says the famous 'Pizzagate' row at Old Trafford was nothing more than "a little unrest in the corridor".

In his autobiography, Sir Alex Ferguson claims the infamous scuffle in the tunnel at Old Trafford in 2004 resulted in a rift with the Arsenal boss which lasted five years.

Ferguson dedicated an entire chapter to his rivalry with Wenger, going on to claim that the Frenchman got "softer" after the infamous match at Old Trafford which ended Arsenal's 49 game winning run.

But Wenger, who claims he is too busy to read the book, insists he was more angry with the referee at the time, Mike Riley.

"I think it was a little unrest in the corridor after the 49th game, refereed by Mike Riley at the time, who is now responsible for the referees," said Wenger of 'Pizzagate'.

"I think on that day, he had not his best day and that brought a lot of frustration on."
