Joe Hart (6.5): Another game, another clean sheet. Hart made one crucial save in the match, as he denied Eden Hazard from close range at the end of a promising counterattack for Chelsea on 70 minutes. It may not have been a highlight-reel-worthy save, but the scoreline was just 1-0 at the time. His best save of the match came in the final minute, as he blocked a shot from Radamel Falcao to keep the visitors off the scoreboard. He once again looked very confident between the pipes and had no issues with crosses swung into the box. Hart is one of just two Premier League keepers yet to allow a goal this season (minimum two games played), along with Sergio Romero of Manchester United.
Bacary Sagna (7.5): Sagna's steady play at right fullback was massive in terms of limiting Hazard's influence on the game. If Sagna continues to look so convincing back there, he could easily once again be considered one of the best in the league at his position.
Vincent Kompany (8.5): Just as Sagna kept close tabs on the speedy winger Hazard, Kompany was strong against the impetuous Diego Costa. Kompany kept a cool head against Costa, with the exception of one reckless challenge on the striker which resulted in a booking. All in all, though, Kompany was excellent. He was a rock at the back and even managed to score another goal off a corner kick. The skipper has two goals in two matches, as he has clearly mastered the near post run.
Eliaquim Mangala (7.5): Kompany's header was a thing of beauty, but Mangala almost had a goal off the noggin as well. He nearly guided a header past Asmir Begovic on the stroke of halftime, and honestly 2-0 would have been a more indicative scoreline at the break given the number of quality chances City had in the early going. He neutralized Costa very well, just as he had done in his City debut a year ago. Mangala has been impressive and reliable at the back so far this season.
Aleksandar Kolarov (7.0): It was good showing by the back line all the way around, and Kolarov played his part very well. He dealt with the powerful Ramires and then did a fine job against substitute Juan Cuadrado. Kolarov pushed forward with purpose and defended with intelligence, cutting off passing lanes and anticipating switches of play. Oh, one more thing: this guy is a beast at set pieces, as he consistently provides beautiful deliveries.
Yaya Toure (7.5): He makes the game look so incredibly easy. He and Fernandinho serve as a strong tandem in front of the back line, which was evident even against the supremely talented Chelsea midfield. Toure helped lock down the middle of the park, restricting Willian and Cesc Fabregas from playing a more free-flowing style. Toure's abilities as a defender in this fixture emphasized just how well-rounded his game is, which was obviously placed in stark contrast with the more one-way skill set of Fabregas.
Fernandinho (8.0): What a hit. No pun intended. His cracking strike in the 85th minute was one to savor for the players and the faithful, as it officially sealed the deal and allowed the celebration to commence. Late in the first half, he received a yellow for an elbow on Costa. Was he lucky to still be on the field in the second half? Regardless, he played a fundamentally sound game and helped facilitate possession while also inhibiting Chelsea from establishing a rhythm.
Jesus Navas (6.5): He exhibits a nice blend of pace and patience, but he did not present Cesar Azpilicueta with too many problems. Chelsea was quite disorganized at the back, though, and City was getting offense from plenty of players. It is not as if Navas needed to have a run at his marker every time he touched the ball.
David Silva (7.5): The catalyst Silva is a nuisance for defenses. Chelsea's back line was reeling at times and just generally looked out of sorts. Silva had his way in the midfield, dictating the pace of the game and floating into pockets of space as he always does so effectively. He got on the ball right out of the gate, which was a big reason why Chelsea struggled to get into any sort of flow early on. He was getting in behind Chelsea's center defensive mids and causing problems. Silva was involved in the first goal, helping City keep the ball in the attacking third and then playing the entry pass to Toure before Aguero finished it.
Raheem Sterling (7.0): He was a handful for Branislav Ivanovic. At times, it did look as though a man was chasing an automobile down the flank. Sterling's pace is troublesome for defenders, and sometimes just drawing free kicks in dangerous areas gets the job done.
Sergio Aguero (8.5): The goal machine nearly finished the game with double-digit scoring chances. He showed great composure in the box on his goal, putting away the chance to give City a 1-0 advantage with just over a half-hour gone. He forced a number of quality saves out of Begovic. The goal was undoubtedly the first of many this season.
Samir Nasri (6.5): Nasri was introduced with 25 minutes left in the match, replacing Navas. He helped City see out the game with his play on the wing.
Martin Demichelis (6.0): Demichelis replaced Sterling in the 79th minute. It was another short work shift for him.
Wilfried Bony (6.0): Bony entered the game with just seven minutes remaining in regulation, but he made a lovely weighted pass on the counter that led to the third goal.
