Jose Mourinho has had some choice words in the past about the atmosphere at Stamford Bridge.
The Chelsea manager has urged fans to be a bit more boisterous, but it was the team that underperformed today.
The Premier League leaders were shocked by League One Bradford City, losing 4-2 after being ahead 2-0 ahead.
The 6,000 Bradford fans in attendance were clearly enjoying themselves and took the chance to rub salt in the wounds of their illustrious hosts. And there was Mourinho being the good Samaritan after the game too when he visited the Bradford changing room in a show of real class.
