West Ham boss David Moyes admits they were flat for defeat to Wolves on Saturday.
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.
Moyes said, "It was not our best today.
"We weren't at our best and didn't play as well as we have done and there were quite a lot of disappointing aspects of our game today, if I'm honest.
"Look, we just about hung in there and tried to keep going but we didn't really play as well as we can, but we mustn't be fooled by Wolves because they're a decent team, in a good league position and have shown good form for parts of the season, so it was a tight game.
"We had players away on international duty but let's not think for one minute that's an excuse because it's far from it.
"We want more international players and I want to bring more to the Club in the future and I want to develop the ones we've got here and help them get capped by their countries. We enjoy seeing our players play for their countries.
"There is part of that and I do agree it gives you less time to work with your players and we had the journey up here on Friday, so all those things do play a part."
