Jose Mourinho last night continued his feud with Arsenal manager, Arsene Wenger, by labelling him a specialist in failure.
The statement came after Wenger suggested that Mourinho's tactics to downplay Chelsea's title hopes was due to a fear of failure.
But while Wenger has succeeded in getting under Mourinho's skin, he would have been shocked by the vicious response.
Mourinho told reporters at his press confrence at Cobham: "He is a specialist in failure, I'm not.
"So if supposing he's right and I'm afraid of failure, it's because I don't fail many times. 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.
"If I did that at Chelsea I'd leave and not come back."
In Wenger's press conference earlier in the day, he was asked why the managers of the other title contenders, Chelsea, Liverpool and Manchester City were playing down their title hopes he replied: "It's a fear of failure.
"If you declare yourself not in the race you cannot lose it, simple as that.
"I just think that our job is to be ambitious and try to win, if we do not win to take full responsibility for that, that's how I see it."
