VIDEO: West Ham 3-0 Genk – The Hammers Continue with the Unbeaten Run in Europa League
As West Ham took a significant step towards the Europa League knockout stage with victory over Genk, forward Jarrod Bowen said "teams will fear us".
Gathogo Wanjiru David Moyes' side maintained their 100% record after three games and comfortably sit top of Group H, six points clear of second-placed Dinamo Zagreb, who were beaten 2-1 at Rapid Vienna.
The Hammers had the majority of the possession but barely threatened in the first half until Craig Dawson looped home a header from Aaron Cresswell's cross on the stroke of half-time.
They took total control with two goals in the space of two minutes just before the hour mark.
Issa Diop headed in via the crossbar from another fine Cresswell delivery, while Jarrod Bowen cut in from the right and fired in shortly after, though goalkeeper Maarten Vandevoordt will be disappointed at not keeping the low drive out.
Bowen told BT Sport: "The main thing is topping the group. The home games are vitally important. We want to win away too.
"If we can stay strong, keep the confidence then I think teams will fear us. We could be the team to look out for. We're only a few games away from a big cup run.
"We'll keep pushing. We're winning games so that makes the players want to put the performances in."
West Ham were rampant and Nikola Vlasic could have converted a quick-fire fourth, but his shot from the edge of the six-yard box was blocked.
Genk were left to rue Paul Onuachu's big chance in the first half when he beat goalkeeper Alphonse Areola to a cross but sent his header wide of an open net.
