- Chelsea lose at home to Crystal Palace
- Result marks only second time Mourinho has lost league match at home whilst in charge of Chelsea
The Portuguese was celebrating his 100th league game at Stamford Bridge but London rivals Crystal Palace spoiled the centenary party by making away with a surprise 2-1 victory.
Bakary Sako opened the scoring for the visitors after 65 minutes before Radamel Falcao leveled matters with his first goal for Chelsea 14 minutes later.
Falcao's strike was assisted by another new signing in the shape of ex-Barcelona man Pedro Rodriguez.
Yet almost as soon as Chelsea was level it was behind once more. Joel Ward reacted to nod home his second goal of the season and ensure a famous victory for the Eagles.
The only other time Chelsea has suffered a home league loss under Mourinho was against a relegation threatened Sunderland in April 2014.
