Thibaut Courtois was sent off as Chelsea started the defence of their Premier League title with a 2-2 draw against Swansea.
Chelsea took an early lead through Oscar before Swansea debutant Andre Ayew equalised on 28 minutes.
The visitors were level for just 90 seconds though as Federico Fernandez put through his own net.
Courtois was dismissed on 52 minutes for denying Bafetimbi Gomis a clear goalscoring opportunity. Gomis then equalised past substitute ‘keeper Asmir Begovic from the resulting penalty to complete the scoring.
Jose Mourinho issued a surprise with his team selection by naming Diego Costa in his line-up after earlier claiming the striker was still struggling with the hamstring injury that ruled him out of the Community Shield.
Costa scored a hat-trick against Swansea in the reverse fixture last season and he was closely guarded by Ashley Williams in the opening stages. However, that focus on Costa couldn’t stop Chelsea taking the lead on 22 minutes.
