Chelsea had Thibaut Courtois sent off as they started their Premier League title defence with a draw against Swansea City at Stamford Bridge. Oscar's free-kick put the Blues ahead before Andre Ayew stabbed a close-range equaliser after keeper Courtois had kept out Bafetimbi Gomis's header. Federico Fernandez put Willian's cross past his own keeper before Courtois was sent off after bringing down Gomis. New signing Asmir Begovic came on but failed to stop Gomis's spot-kick. Swansea played with an extra man for more than half an hour but could not make the most of the advantage.
