Cech is adamant that he and his teammates are focused solely on winning football matches at Stamford Bridge, and insists that Saturday was no different.
He told the club's official website: "I'm so focused on the game that I hardly understand what the people sing or shout or what they do.
"The main point is the people were here, the stadium was full, they were behind us, they supported the team and we won the game.
"We had a good performance and everyone seemed to leave the stadium happy. Overall our performance was very good. Everybody was focused, everybody was concentrated until the last whistle."
The Blues are fourth in the Premier League with a five-point cushion above Arsenal in the race for Champions League qualification.
