Mourinho's rivalry with Wenger began in 2005 when the Gunners head coach questioned the Portuguese's tactics and that sparked a war of words between the two ever since.
Here are some the best quotes:
2015 - Mourinho's Specialist in Faliure rant.
"Am I afraid of failure? He is a specialist in failure. I'm not. So if one supposes he's right and I'm afraid of failure, it's because I don't fail many times. So maybe he's right. I'm not used to failing. But the reality is he's a specialist because, eight years without a piece of silverware, that's failure."
2005 - Wenger's response to Mourinho calling him a 'voyeur'.
"He's out of order, disconnected with reality and disrespectful. When you give success to stupid people, it makes them more stupid sometimes and not more intelligent."
2010 - Wenger accused Mourinho's Real Madrid of getting booked as a tactic in order to serve suspension in an easier Champions League game.
"When you see how it looks on television, it is the best demonstration to think: 'Never do that again'. It looks, frankly, horrible. It's a pity to see that from a big club."
2010 - Mourinho's response to Wenger's UCL tactic jibe. "Instead of speaking about Real Madrid, Mr Wenger should speak about Arsenal and explain how he lost 2-0 against a team in the Champions League for the first time. The history about the young kids is getting old now. Sagna, Clichy, Walcott, Fabregas, Song, Nasri, Van Persie, Arshavin are not kids. They are all top players."2015 - Mourinho mocking Wenger's Premier League title drought.
"There are some managers, the last time they won a title was 10 years ago, the last time I won was a year ago. If I have something to prove, imagine the others! To finish 4th is not the aim."
