West Ham attacker Jarrod Bowen said that "teams will be fearing us" after the Hammers made it three wins from three games in the Europa League group stage.
The other three teams have one win apiece.
"The main thing is topping the group," Bowen told BT Sport. "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 be fearing 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 keep wanting to put the performances in."
