It was good game to watch. Looked like City were controlling the game but that was the case against Chelsea as well, and we saw the result there. Liverpool had their chances and this could easily gone both ways. I don't like the Liverpool starting midfield line, most of the times they haven't put any effort of making the attacks. City did some pressing it let to many wrong long passes by Liverpool and City gaining the ball again fast.
The Etihad stadium was able to provide strong confidence in the Manchester City team, even Manchester City was able to give satisfaction because it could lead ahead of the first goal given by Sergio Aguero in the first round. however, the attack given by Liverpool in the 17th minute was very tense because it almost scored earlier if it was not thwarted by the goalpost. but until the match is over Manchester City can win the match and have an additional 3 points and success gets back to second place in the standings
I believe the league is still open to fight for now that the points have been bridged to 4 points and there are plenty of games to play. I think Liverpool look fantastic even in defeat and should they continue like this it will be difficult for the other teams to claim the title this season.
