The Belgian shot-stopper, who struggled with a knee injury prior to the start of the match, gave away the game-tying penalty after tackling Bafetimbi Gomis.

This wil be a day Thibaut Courtois will want to forget soon. The Belgian goalkeeper left Stamford Bridge's pitch after being red carded, seconds after tackling Bafetimbi Gomis as he approached his net. With the penalty kick awarded to the Swans, Garry Monk started another season with the Welsh side shocking one of the EPL's big teams, but he will have to thank the shot-stopper for it.

Prior to the game's kick-off, Courtois fell to the ground, apparently after picking up a knee injury. The team's doctor decided he was fit to start, but his form during the first half seemed to be a little dubious. Chelsea were on top after Oscar's free-kick goal, but Ayew's strike leveled things. Forty seconds later, Willian's shot was deflected into the back of the net by Federico Fernandez, giving Chelsea the lead after the first 45 minutes.

But things turned out the wrong way for the Blues after the break. Swansea came close to Courtois' net, and following a failed offside trap by Chelsea's defense, Gomis found himself alone against the Belgian, who had no choice but to tackle him. The ref awarded the penalty and sent off Courtois, while substitute Asmir Begovic was not able to stop Gomis' shot.

Chelsea's two-point drop at home was something some fans enjoyed. Here are the best comments about their draw and Courtois' performance.
