West Ham picked up where they left off against Wolves last weekend with another impressive display to end Leicester's 100% winning start to the season.
Boss David Moyes was again absent from the touchline as he continues to recover from coronavirus, but as in last weekend's 4-0 victory, it did not hamper the Hammers, who offered an excellent balance of graft and guile.
Ruthless on the break, they did a similar job on Leicester to the one the Foxes did in their brilliant 5-2 win at Manchester City seven days prior.
Michail Antonio scored the first, heading in at the back post from Aaron Cresswell's pinpoint cross from deep after the striker had himself found his team-mate with a quickly-taken free-kick.
