West Ham fullback Aaron Cresswell says they cannot dwell on defeat to Wolves.
Raúl Jiménez's second half strike was enough to keep the points in the Midlands and end a run for the Hammers which had taken in seven games in all competitions.
“We found it really frustrating," Cresswell told the club's website. “I thought we had a good spell for the first 15, 20 minutes, but after that, credit to Wolves – they played some fantastic stuff and we couldn't really get going.
“We created a couple of chances but we didn't really have that edge to create more.
“They were rotating a lot, getting their two wide men in, which was causing us problems at times. We were getting caught between whether to go in or whether to stay.
“The manager changed a few things at half-time and altered a few tactics, and, look, it's frustrating on our part, certainly with the start to the season we've had.
“But we can't get down on one defeat, we've got to get going again."
