Mourinho, whose champions and league leaders have a 14-point advantage over the Gunners, has urged Wenger to concentrate on improving his own club's results before talking about Chelsea.

The Portuguese was infuriated by Wenger's decision to comment about Chelsea's 1-1 draw at Everton last Sunday and their FA Cup loss to Charlton on penalties in midweek.

Wenger had said that some of Chelsea's self-belief disappeared after those two results and that hope had been restored to those clubs involved in trying to catch the runaway league leaders.

Mourinho responded by suggesting the Arsenal chief is clearly rattled by their success.

"I think he is one of these people who is a voyeur," said Mourinho after watching his side destroy Blackburn 4-2 at Stamford Bridge to make it 10 wins out of 11 in the league this season.

"He likes to watch other people.

"There are some guys who, when they are at home, they have a big telescope to see what happens in other families. He speaks and speaks and speaks about Chelsea.

"It bothers me because the guy is speaking all the time. We never speak about them.

"You can do it when you are top and you have a big morale. When you are on game number 11 and you still can't win away from home, and when you are without Thierry Henry and he can't win a game, he should be worried about them.

"He's worried about us, he's always talking about us. It's Chelsea, Chelsea, Chelsea, Chelsea.

"I might be worried if my team made a defensive mistake. I shouldn't be worried about what Arsenal did at Tottenham. They are always speaking about the other families.

"I don't know if he wants my job, I don't know. He loves Chelsea."

The Blues now travel to Seville for a Champions League clash where victory will ensure a place in the knockout rounds.

However, Argentinian striker Hernan Crespo has not travelled to Spain to face Real Betis after picking up a muscle injury in Saturday's victory.

But winger Damien Duff made the trip and may start the game on the bench.
