However, in a new and explosive book on Mourinho by journalist Rob Beasley which is being serialised by Sportsmail, the extent of their hatred has reached a whole new level:
‘I will find him one day outside a football pitch and I will break his face,’ Mourinho allegedly said in regards to Wenger.
The quotes from the now Manchester United boss may come as little surprise following his words after their display of fisticuffs on the Stamford Bridge pitch.
It was October 5, 2014 when Chelsea defeated Arsenal 2–0 but the game is best remembered for an angry pushing between the managers on the touchline rather than the goals from Eden Hazard and Diego Costa.
‘He [Wenger] was asking for a red card and pressing the ref in my technical area,’ Jose said of the incident. ‘I told him to go back to his area. He pushed me.
‘I told him, “Here you do that, you know I can’t react, but I will meet you one day in the street”.’
It was shortly after this incident the two teams faced each other once more and, in typical Mourinho fashion, he would have the last laugh.
In Wenger’s 1,000th game as a manager Chelsea humiliated the Frenchman with a stunning 6-0 victory at Stamford Bridge.
