The Chelsea manager took exception with Arsene Wenger’s movement out of his technical area to complain at a refereeing decision and argues that Martin Atkinson helped the Gunners.

Chelsea continued their fine record against Arsenal with a hard-fought 2-0 Premier League win that was more than a little ill-tempered.

Eden Hazard scored the opener from the penalty spot in the first half after Laurent Koscielny fouled him in the box, his cool spot kick sending Wojciech Szczesny in the wrong direction.

Playing against the Gunners for the first time since joining Chelsea this summer, Cesc Fabregas provided a delightful assist for the second goal as, with just over 10 minutes of normal time left, he lifted the ball over Arsenal’s defence for Diego Costa to chase and finish with aplomb – the striker’s ninth goal in seven league games this season.

The two managerial foes clashed in the first half after Wenger reacted angrily to Gary Cahill’s dangerous tackle on Alexis Sanchez with the Frenchman shoving Mourinho in the chest.

Mourinho claims there was nothing major in the clash insisting he had no problems with Wenger pushing him.

Asked about the Wenger incident, Mourinho told Sky Sports: “For me, it is over. But the technical area is very clear – I have mine, he has his and he cannot come to mine, especially to put pressure on the referee to give a red card to my player.

“So I just told him ‘leave my technical area and don’t come back please’.”

Then asked if it was a big deal that Wenger had put his hands on him, Mourinho said: “No, it is no problem.”

Wenger insisted he had “nothing to regret”, adding: “I wanted to go from A to B and somebody stopped me in between.

“The B was to see how badly Sanchez was injured.”

Mourinho did feel Arsenal could have finished the game with eight men suggesting Laurent Koscielny, Calum Chambers and Danny Welbeck were all fortunate to escape red cards from referee Martin Atkinson.

“I think the referee, from a technical point of view, had a fantastic performance in a difficult, technical, fast match with lots of runs behind – also the linesmen had a difficult game and I think they did a fantastic job.

“But Arsenal could have finished with eight men, because it is a red card for Koscielny, it is a double yellow card for Chambers in the first half, and clear was a red card for Welbeck.

“But I accept that the Welbeck red card was not given – the game was over and Welbeck is a good kid and is not aggressive. It was just maybe a reaction, some frustration.

“So I have no complaint really but my boys are doing fantastic we beat a good Arsenal.”

Mourinho was delighted with his side’s victory as they moved five points clear at the top of the table thanks to Eden Hazard’s 1st half penalty and Diego Costa’s goal 10 minutes before the end.

“It was a difficult game,” noted Mourinho. “They started better than us, but Eden gave us the penalty and the first goal and the game could have finished there if it had been a red card.

“At the end of day they had more of the ball than us but we had the chances so we scored two goals, we won and I am happy we beat a good team.”
