Joe Hart (6.5): Hart has not really been tested by any of City's opponents thus far, and Watford was no exception. It was another clean sheet for him on a pretty relaxing afternoon between the sticks. Hart is yet to concede, while City continue to find the back of the net at the other end (read as: goal difference of +10).
Bacary Sagna (7.5): Sagna provided a lovely assist to Sterling for the opening goal. He runs the flank well, whips in dangerous crosses and defends diligently. He made an outstanding block on one of Watford's only scoring chances. Yes, Saturday's contest was one-way traffic. Yet while no one on the back line was pushed to his limits against Watford, the concentration was there and the defending was assertive from Sagna and company.
Vincent Kompany (7.0): He was commanding at the back and removed any shred of danger Watford managed to present. Kompany has completed his return to beastly status.
Eliaquim Mangala (7.0): His bumpy start at the club is starting to feel like ancient history. He obviously was never going to have the toughest game against a defensive-minded Watford side, but he has made some noticeable improvements to his game, starting and ending with looking like a much more confident center-half.
Aleksandar Kolarov (7.0): Steady. That is the word that comes to mind with Kolarov. It was not a frantic day at the back, but he continues to play at a high level. He got a few touches with Nasri on the left in the second half when Sterling shifted to a more central role on the pitch.
Yaya Toure (7.5): His sheer presence in midfield is simply brutal for opponents. It was not really anyone's most spectacular game, but Toure was rocklike yet again. He almost scored a beautiful goal after a lovely sequence of passes from City. The miss is worth noting because the left-footed curler from the edge of the area would have been one of the best goals of City's campaign.
Fernandinho (8.5): He is a holding mid who is scoring in every other game at the moment. His goal on 56 minutes doubled City's lead and gave them plenty of breathing room. It was a glorious finish by a player who has enjoyed a glorious start to the campaign.
Jesus Navas (7.0): Navas had an abbreviated outing, as he was replaced by Nasri at halftime. He was workmanlike as always, but he played in the far less exciting half of action.
David Silva (7.5): City were uncharacteristically quiet in the first half, but Silva's quality shined as the match carried on. Silva fed Fernandinho for the second goal, as he continues to average an assist per game.
Raheem Sterling (8.0): City's first half was quite subdued by their lofty standards, but they came out after the interval absolutely roaring. Sterling played his part, netting his first Premier League goal within minutes of the start of the second half. Watford were not going to be able to hang on for another 45 minutes by sitting back, and Sterling made the visitors aware of that. Great movement, great finish. He is on the board before September.
Sergio Aguero (7.0): He works, and works, and works. He may not be on track for another 26-goal season (yet), but his unwavering effort puts tremendous pressure on back lines. He occasionally drops deep to get a hold of the ball, and he always looks like a dangerous option when City are streaming forward on the counter, as they did several times in the second half.
Substitutes:
Samir Nasri (7.0): Nasri took over for Navas in the second half. He continues to perform very well despite the fact that he is not in the starting XI. Nasri moves all over the place, as he is effective on both flanks and creates well in the final third.
Fabian Delph (6.0): Delph replaced Silva with a 15 minutes remaining in regulation. He connected a handful of passes and moved well in midfield, but his time out there was rather brief.
Kelechi Iheanacho (6.0): It was a blink of a senior debut for the 18-year-old, as he replaced Sterling in the 89th minute.
