Diego Costa struck twice for Chelsea as the Blues secured a 2-2 draw in a controversial game at Swansea City.
The Spaniard opened the scoring in a dominant first-half performance from the Blues, before the hosts fought back to equalise and then take the lead in quick succession; Gylfi Sigurdsson and Leroy Fer grabbing the goals.
However, Costa managed to grab the equaliser in the final 10 minutes - although there were calls for him to not even be on the pitch at that moment following a series of indiscretions.
Willian stung the palms of Fabianski five minutes in, as Chelsea dominated the early passages of play.
