Manuel Pellegrini far from happy despite crucial win for Manchester City
Manuel Pellegrini saw his side arrest an alarming three-match winless run after defeating derby rivals Manchester United yesterday.
But the Manchester City boss was disappointed by the way his charges switched off after getting their goal through Sergio Aguero.
He said: "I'm very happy with three points. We must win and we played very well up until the moment we scored the goal.
"After that we maybe finished playing thinking that the game was over, but it wasn't over."
Pellegrini's only gripe was with referee Michael Oliver, who waved away several penalty shouts.
The most plausible appeal came in first-half injury time when Marcos Rojo kicked Yaya Toure as he was about to shoot following a masterful chip by Aguero.
"It is unbelievable we didn't get a penalty (for the foul) against Yaya Toure," Pellegrini added.
"It was not only a penalty but also a sending off because he was the last man. There were two others against Sergio but we are not talking about that."
Pellegrini was also dealt a defensive blow before the match even kicked off as Aleksandar Kolarov picked up a problem in the warm-up.
He revealed afterwards that the Serbian left back is unlikely to return for City's clash with Roma this week.
City skipper Vincent Kompany revelled in securing bragging rights over their Manchester rivals again as they extended their recent derby dominance to four wins on the bounce.
"Winning this game gives us an edge in our city, again, and the rest is a boost for us. We did our job and we're happy with that."
In contrast to City's delight at winning the three points, United captain Wayne Rooney insisted that "for long periods we were the better team".
"Our pace was causing them problems. You could see they started panicking at the end, kicking the ball long. We just couldn't get that moment in the final third to get the equaliser," he said.
"You can see every week we are getting better and we're not far away from being back up there and being a very good team. It won't be long before we are."
