David Moyes admitted West Ham simply couldn't cope with Manchester City's new tactic in their Premier League opener, as they'd never seen the Blues use it before.
Barring a couple of periods of pressure from West Ham, City controlled proceedings at the London Stadium, helped in a large part by full-backs Kyle Walker and Joao Cancelo, both operating as inverted full-backs to join Rodri as a midfield three.
City have perfected using one inverted full-back in the last two years, but Moyes said West Ham were helpless to combat both Walker and Cancelo playing centrally as they simply weren't expecting it.
