Manchester City boss Manuel Pellegrini was bitterly disappointed after his side's 2-1 home defeat at the hands of Tottenham Hotspur.
Spurs took the lead after referee Mark Clattenburg awarded a controversial penalty to the visitors after Raheem Sterling was penalised for handball, a decision the Chilean branded as "absolutely wrong".
"It was a penalty that referee Mark Clattenburg wanted to sign for and he gave the sign," Pellegrini told BBC Sport.
"It was absolutely the wrong decision, it hit the back of Raheem Sterling then his elbow. Sterling was not even seeing the ball. It was the same referee in the first game where they were two clear goals in offside and we lost 4-1.
"It was the key moment that decided thee game, before that they did not shoot towards our goal and did not have any chances. We took the risks, the spirit of the team was good but it was not enough.
"The response of the team i am very happy about. The spirit in the game was good but you win with goals. We made an important mistake in the second goal and penalty we did not deserve.
"We are going to continue fighting until the end. We still have 36 points to play for and are only six points behind the leaders. We will not give up and continue working and improving."
