Joe Hart (8.0): Hart lobbed in a contender for save of the season when he soared to the top corner to deny Dimitri Payet's free kick. The goalkeeper was hardly the culprit on the two West Ham goals (both scored by Enner Valencia). However, neither shot rocketed past him, and it looked as though he would maybe be able to keep one or even both out. Both goals came from close range, though, as Hart once again provided no reason to doubt him.
Bacary Sagna (7.5): The consistent Sagna is such a threat moving forward, and he rarely falters at the defensive end. City's back line was not at its finest against the Hammers, but No. 3 took care of business on the right flank.
Nicolas Otamendi (6.0): Mental lapses happen. Tactical mistakes happen. Even great defenders like Otamendi are bound to err from time to time. But getting beaten on a long throw-in is just plain disheartening. Valencia got in behind the Argentine and made City pay a hefty price. His night was decent overall, but the phantom defense on Valencia's second goal was quite costly. Otamendi was really trending in the right direction prior to this match, so hopefully it was a mere hiccup in what has been an impressive campaign thus far.
Martin Demichelis (6.5): He seems to improve as games carry on. The home side were able to throw some promising attacking moves in City's direction, but Demichelis dealt with the danger well enough. Valencia has elite pace and quickness, so Demichelis had quite a respectable performance.
Gael Clichy (6.5): Payet is creative and technically gifted on the ball, and his movement off the ball is troublesome for opposing defenses. Having said that, Clichy did reasonably well against the dynamic attacker. Sure, Payet presented the left-back with some problems. But this was just Clichy's fourth Premier League outing of the season, and he was tasked with facing one of the league's best players of the current campaign. Clichy should be able to provide more offense in the future.
Yaya Toure (6.5): He did not track runners particularly well on defense, and his contributions on offense were limited due in large part to how deep he was sitting. It was certainly not the Ivorian's most dominant display.
Fabian Delph (7.0): His bobbling shot bounced off the pipe in the early moments of the second half. He would have put City ahead 2-1 if he had scored, but alas, the ball stayed out. He was so good against Palace last week, but he came back down to earth in this game.
Jesus Navas (7.0): The Spaniard was full of energy on the right flank. Shocking, I know. A real catalyst, Navas can change games with his speed and industrious play. The only problem in this match was that his work rate did not directly translate into offensive output. A portion of the credit for West Ham must be given to Aaron Cresswell, who is becoming more and more of a household name and did well against the shifty Navas.
David Silva (6.5): The man looks mortal. He figures to return to his World XI level relatively soon, but for the time being, he just looks like a guy with a deft touch who finds pockets of space well. He does not look like arguably the best CAM in the league (which he is capable of being, along with Mesut Ozil of course).
Kevin De Bruyne (6.5): Much like in last week's game against Palace, KDB had a minimal impact on the game by his standards. His touches were limited, and he was never able to depress the "beast mode" button. When he and Silva return to demigod status, it is difficult to see how any team will be able to contain this offense. But at the moment, the Belgian is exceptionally quiet.
Sergio Aguero (9.5): Whoa there. Aguero was straight feeling it from the moment he stepped onto the pitch. He was unlucky to hit the post on seven minutes after a lovely dink over Adrian. Just moments later, though, he drew a penalty and was able to cooly tuck the ball into the bottom corner from the spot. He doubled his money late in the match to draw City level, making his way into the box and punishing West Ham with a deadly finish. It is not the first time he has played the role of hero for this team.
Raheem Sterling (6.0): He was never able to really alter the game after replacing Navas on 67 minutes. In these games it seems fair to look back and wonder what he could have done had he been in the starting lineup.
Kelechi Iheanacho (7.0): The precocious Iheanacho entered the fold on 76 minutes and was very productive. He was an integral part of the late Aguero equalizer. Are increased minutes on the way for the youngster?
Fernando (N/A): The midfielder earned a yellow card in his short time out there, but that was about it.
