West Ham's next fixture is against Liverpool in the league later this month. "We believe more in our work, and it is better for us but we know if we don't work and don't run we will not win".
But when Arnautovic, fit again after three games out injured, began to get on the ball West Ham looked a totally different team, especially to the one which surrendered so meekly at Brighton last weekend.
Watford actually carved open the first opportunities of an open game, Etienne Capoue with a shot deflected over and, from the corner, Adrian Mariappa's header forcing a smart save from Hammers goalkeeper Adrian.

"We try to look for consistency and to be more compact", said Gracia. West Ham won the match 2-0. We will not be signing a player that the manager hasn't seen play, and we hope we will spend our money better.
Fans were disappointed with a lack of incoming players at the London Stadium on deadline day, with striker Jordan Hugill's arrival from Preston the only first-team acquisition.
"I know how we got those points - running a lot, and working a lot - and I think this is the key to the future". The latter was practically electric throughout the contest, producing the ideal crossing assist for Hernandez to head home in the 38th minute to give the Hammers the lead. "In fact he should have scored more".
In a candid interview with West Ham TV about the future of the club, Sullivan added: "I want to speak directly to the supporters and say how important it is that we all pull together during these times".
