Chelsea goalkeeper Petr Cech has said that he is "extremely disappointed" after his side's 5-3 defeat at home to Arsenal.
The Blues had led twice at Stamford Bridge, but two late Robin van Persie goals sealed the win for the Gunners.
"I am extremely disappointed about the result," Cech said on his official website. "But there is nothing we can do about it now - the only response is to win the following games.
"We gave Arsenal too many chances to punish us and they took them."
Cech and his teammates travel to Belgium to face Genk in the Champions League on Tuesday.
