Jose Mourinho has attempted to throw fuel on the fire that has engulfed his relationship with Arsenal boss Arsene Wenger.
The Chelsea manager has failed to see eye-to-eye with his Premier League rival on a number of occasions, but the controversy that followed his team's 2-0 victory over the Gunners last weekend has threatened to deteriorate matters further.
Arsenal were unhappy with Diego Costa's actions during the game with the Frenchman incredulous that Mike Dean had not sent him off. That decision would eventually lead to Arsenal defender Gabriel Paulista seeing red.

The FA have since looked at the incidents and have decided to rescind Gabriel's red card whilst also handing a three-match ban to Costa.
Once again, Mourinho claims there is one set of rules for Wenger and another for everyone else. Predictably, he also suggested that his rival has not experienced enough success to justify his position as Arsenal manager.

"In this country, only one manager is not under pressure," Mourinho told reporters.
"Every other manager is. I am under pressure, Steve (McClaren) is under pressure, Pellegrini is under pressure, Brendan (Rodgers) too. We cannot be below par. We have to meet the objectives.
"I have sympathy with all of them because it's a difficult job. There's one outside that list, but good for him. I have sympathy for Steve."
"He can not achieve, keep his job, still be the king"
Asked to confirm who was the one manager he was referring to, Mourinho said: "You know. The one who can speak about the referees before the game, after the game, can push people in the technical area, can moan, can cry in the morning in the afternoon, nothing happens.
"He can not achieve, keep his job, still be the king. I say just one."
Wenger has certainly had a free reign at Arsenal despite coming under pressure from disgruntled fans from time to time.
However, having won three Premier League titles, six FA Cups, and also playing an instrumental role in the building of the Emirates Stadium, some feel he has earned the right to choose his own destiny.
Mourinho, on the other hand, has never managed a club for longer than three seasons but, in that short space of time, has consistently delivered major trophies.
Indeed, in Arsenal's nine-year drought between 2005-2014, Mourinho won five league titles in three countries as well as his second Champions League.
