Watch! Mourinho takes blame for playing a Chelsea player who played 'bad' in loss vs Palace [Video]

Chelsea manager Jose Mourinho is the "unhappy one" at the moment as his side lost to Crystal Palace at the Stamford bridge today.

The match ended 1-2 in favor of Alan Pardew's side who looked to be more organized than their opponents.

In his post-match interview, the Chelsea manager claimed that his team should have been awarded a penalty and also blamed a particular player who played badly in the game.

"The goal is another mistake, I have a player that minute one to minute 90 he was not in the game and maybe my fault because I believe in him and when a player is playing so bad, the best thing is to take him off but I kept him for 90 minute and I was punished by that, so my mistake." - Jose Mourinho

Who could this mystery player be? Any guess?
