LONDON • Jose Mourinho delivered a clear sign he was fuming about the decision that cost Chelsea goalkeeper Thibaut Courtois a red card and handed Swansea the chance to secure a 2-2 English Premier League draw from the penalty spot on Saturday.

The Blues manager refused to comment on the incident that saw the Belgian goalkeeper challenge Bafetimbi Gomis on the edge of his penalty area in the 52nd minute at Stamford Bridge.

The striker went to ground, which prompted referee Michael Oliver to send off Courtois and point to the spot.

Gomis converted the penalty that allowed Swansea to equalise for the second time.

It ultimately denied Chelsea the opportunity to begin their EPL defence with a victory.

Mourinho remonstrated angrily when the decision was made.

But his silence, after the game, spoke volumes as the manager made it clear that he was reluctant to go public with his feelings about the incident.

Asked to comment about the decision, the Portuguese said: "First game of the season, I don't want to start in the first game."

He confirmed he had seen a replay of the incident and insisted he attached no blame to Courtois.

The manager has repeatedly fallen foul of the FA after publicly criticising match officials.

Earlier this year, he was fined £25,000 (S$53,600) for comments that he made following his side's visit to Southampton.

Then, he complained of a "campaign" to influence decisions against his team.

Mourinho's unwillingness to discuss Oliver's performance suggested he might have started the new season with a resolution to keep his opinions about refereeing decisions to himself.

But the Portuguese denied this and said: "No, it is just because the first time I can control myself.

"I want to react this way so you don't see he was (complaining) from day one. In day one, we were punished but it was not on day one that I opened my mouth."

Chelsea's failure to see out a game they had twice led inevitably throws focus on the lack of development of the squad since May when they won the title.

Mourinho was last week forced to defend the club's approach which stands in contrast to those of Manchester City and Manchester United who have invested heavily in their squads.

And while this result is unlikely to force a late change of policy in the final weeks of the transfer window, criticism is sure to mount if Chelsea suffer many more disappointments. "I think you don't expect me, after a bad result, to come here and speak about the squad, the players, the transfer window and investments of other teams," he said.

"Playing with 10 men for such a long time is much more difficult and fundamentally I am happy with the quality they had in the first half and I am happy with their spirit in the second half so we are in peace."

Mourinho also launched into a bizarre rant at his medical staff when Sky Sports interviewed him.

His team medics had rushed to treat forward Eden Hazard near the end of the game, with the Blues still vulnerable to defeat. Mourinho said: "When you go to the pitch to assist a player, you have to be sure the player has a serious problem. And I was sure that Eden hadn't a serious problem.

"He'd had a knock, he was very tired and my medical department in their impulse were naive and left me with eight outfield players."
