One unconvincing waft at a corner in the second half, but he had a gentle introduction to life in the Premier League and was not needed to show hi skills as an 11th outfield player. 6
Vincent Kompany
Guardiola was not entirely happy with some of his distribution, but Kompany proved his worth with some acrobatic, sinew-testing interceptions and heroic blocks. 7
John Stones
Had very little to do, but he was assured and secure in what he DID have to do, and the building of him as a quality defender continues - looks better in this back three. 7
Nicolas Otamendi
Had one or two headless moments but recovered those situations himself and was part of a secure defence which was hardly tested by a retreating Seagulls outfit. 6
Kyle Walker
From his first attacking dash down the right, followed by an overlap that teed up Aguero for a chance, he was a prime offensive weapon for the Blues - and he did not stint on his defence either 8
Kevin De Bruyne
For 70 minutes he wavered between ordinary and awful but then, as class players do, he burst into life with a swift tackle, and quick pass to Silva which created the opening goal. 6
Fernandinho
Beavered away in the heart of midfield but until his cross forced the second goal he lacked the creative edge which Yaya Toure brought to that area for much of last season - a genetic splicing of those two players is required, Abu Dhabi! 6
David Silva
With so much expected from him in every game, Silva rarely disappoints, but he did this time. A uncommon number of misplaces passes and misunderstandings - and then a cute pass to set up Kun for the opener. 6
Danilo
Filling in until Mendy gets fit, and while he is steady and athletic, his lack of a left foot was absolutely glaring - everything was shifted back onto his right, and it made him easier to deal with. 6
Gabriel Jesus
Eventful day as he was booked for handling one into the net, missed an absolute sitter and produced a lovely piece of skill by lifting the ball over Dunk early on. 6
Sergio Aguero
Was largely anonymous until he messed up his first big chance, but when he got another opportunity he sank it to set City on their way to victory. Not a great display, but he's off the mark! 6
Substitutes
Sane (for Danilo 68) Doesn't look happy at wing back 6
