A bizarre game in which a David Luiz own goal and Robin van Persie effort put the visitors two up. Juan Mata and Ramires netted either side of the break to bring Chelsea level, only for them to be reduced to nine men as Branislav Ivanovic and Fernando Torres were sent off. Javier Hernandez had the final say 15 minutes from time, with accusations of racist language then levelled by Chelsea against referee Mark Clattenburg. He was later cleared of any wrongdoing.
