The Citizens entered the final day of the 2023-24 season sitting at the top of the table and two points clear of rivals Arsenal in second, knowing that victory over the Hammers or matching the Gunners' result against Everton would clinch the title.
Pep Guardiola's men burst out of the traps and Premier League Player of the Season Phil Foden sparked a carnival atmosphere when he scored twice in the opening 18 minute - his first a sublime long-range strike in the second minute before slotting home his second from close range.
It was backs against the walls for West Ham, but they grew into the game slightly towards the end of the first half and pulled one back courtesy of a remarkable bicycle kick from Mohammed Kudus.
Man City remained in control after the interval and their patient build-up play was eventually rewarded when Rodri - a man who loves the big occasions in a sky blue shirt - passed his shot from the edge of the area beyond the outstretched left glove of Areola and into the bottom corner.
Nerves were jangling momentarily for the hosts when West Ham thought they had pulled one back through Tomas Soucek, three minutes from, but VAR intervened to confirm that the Czech midfielder handled the ball past Ortega, and Man City saw out the final few minutes en route to Premier League glory... again.
