West Ham United spent eight of the nine seasons in the Premier League and one, 2011/12, outside it. Take City out and every one of the eight reads the same: up one place.
That place is City’s. Every club below City moves up one when City go. West Ham never climb further, and never fall short of it. Seventeenth becomes 16th in 2009/10; 20th becomes 19th in 2010/11; 7th becomes 6th in 2015/16.
It is not for want of results against City. West Ham played them 16 times, won two, drew three and took 9 points. Take City out and all 9 come off, and in no season is it enough to cost them a place. The free place absorbs it every time.
Even the game that settled a title changes nothing for West Ham. The 2013/14 season ended with City’s 2–0 win over West Ham, goals from Nasri and Kompany. Take City out and the game goes, and West Ham’s 40 points stand: 12th of 19.
The season outside the Premier League ended on 19 May 2012, with a 2–1 win over Blackpool in the Championship play-off final.
