Arsenal take on Chelsea this afternoon, which of course means Arsene Wenger and Jose Mourinho will also go head-to-head at Stamford Bridge.
The pair have certainly had their fair share of needle since Mourinho arrived on English shores.
Mourinho has claimed that Wenger is 'obsessed' with Chelsea and is a 'specialist in failure'. Wenger has said he is 'embarrassed' for Mourinho and that he is afraid to fail.
These two are not going to share a glass of wine after the game.
But the fact remains that Mourinho has one up on Wenger. Not only did he smash Arsenal 6-0 in Wenger's 1,000th game in charge last season but Wenger has never beaten Mourinho.
In the past ten years Mourinho has won six domestic league titles, five domestic cup titles and the Champions League twice with the clubs he has been at. Wenger has struggled in the past decade.
On Soccer Saturday yesterday Charlie Nicholas, who played over 200 games for Arsenal back in the 1980's, was asked if he sometimes wishes that Mourinho was the Arsenal boss - and this was his answer:
"Yes [I have wished he was Arsenal manager]. As I say I have never been a lover of his style. I always go back to the time when I was following Celtic and he was the Porto manager. They beat Celtic in the UEFA Cup final. All you wanted to do was say how good they were at times but they dived and they did everything in the game and they would con referees. There was a lot of agitation that I felt about them. But there is no denying that this guy is absolutely fantastic at getting big results."
