'I will find him one day and I will break his face'

Details of Arsene Wenger's fierce rivalry with Jose Mourinho are set to be revealed in an explosive new book Jose Mourinho: Up Close and Personal, written by Robert Beasley.

While Mourinho has tried to simmer feuds with the likes of Pep Guardiola and Claudio Ranieri in recent years, his hostility with Wenger lingers on.

The most iconic moment from their rivalry comes from the day the Frenchman shoved Mourinho on the touchline in frustration in 2014.

The explosive moment occured in the same season that Mourinho sold Juan Mata to Manchester United, prompting Wenger to say he was surprised given that Chelsea weren't scheduled to face United again that season.

Beasley explains in an excerpt in The Daily Mail: "Mourinho saw this as yet more evidence of Wenger's obsession with all things Chelsea but for once he bit his tongue. That all changed the following month.

"Wenger had made a thinly disguised dig about Mourinho deliberately playing down Chelsea's chances of being crowned champions because of a 'fear to fail'. It was too much for the ultra-competitive Mourinho to resist, so when he was asked about Wenger's comments he let fly.

"'You know, he is a specialist in failure. Eight years without a piece of silverware, that's failure. If I do that at Chelsea I leave London and I don't come back.'

"Mourinho had carried out a cold-blooded assassination of his enemy in broad daylight. Inevitably it was too gory for some, who believed Jose's brutal honesty was too vicious and vindictive. Not to him it wasn't.

"A few days later he was still pumped up about it all, telling me: 'When Mr Wenger criticises CFC and Man United over the deal with Mata...I will find him one day outside a football pitch and I will break his face.'"

On the infamous shove at Stamford Bridge, Mourinho said: "I asked Jose what had happened and he revealed: 'He was asking for a red card and pressing the ref in my technical area. 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".' Now I don't think Jose was ever serious about having fisticuffs with the Frenchman, he was just huffing and puffing and letting off steam.

"I gave him the benefit of the doubt on this occasion, even though an article for me with Jose saying, 'Let's sort this out in the street, Arsene' would have been huge."
