Diego Costa scored his 21st goal of the season to level the scores after Alexis Sanchez’s controversial opener for Arsenal in the first half. Ramsey restored Arsenal’s lead immediately after Costa’s goal.
Speaking after the game, Costa revealed Chelsea lost because we were a little off coming into the match.
“I guess we were a little off coming into the match, while Arsenal showed they wanted to win it,” Costa said.
“They scored once and had the chance for a second during the first 45. We came better for the second half and scored the equalizer, but they went ahead soon after. It happens, I want to congratulate them for the fine display.”
