Mark Noble has called for calm after West Ham United's 3-0 Barclays Premier League defeat at Swansea City.
The Hammer of the Year admitted that defensive errors and missed chances had left Sam Allardyce's side with little hope of collecting points at the Liberty Stadium, but insisted that the manner of the defeat would not be repeated anytime soon.
Instead, Noble said the mistakes and profligacy that cost West Ham dear in Wales would make them even more determined to put things right when Fulham visit the Boleyn Ground on Saturday.
"We started really well," the No16 pointed out. "We knew Swansea like to pop it about and really play football and we stopped that early doors, but then we obviously let in two silly goals. Apart from those goals, I don't think they had another clear chance in the first half. We had an uphill task after that.
"We put them on back foot early on. We had a game plan and until their first goal it worked. Our set-plays caused them a lot of trouble and we were unlucky not to get a couple of goals, but at this level you can't afford to make mistakes because you get punished.
"Obviously if we'd gone in 2-1 down or even level at 2-2 with the chances that we had, it would have made things different. It was all down to us with the mistakes that we made. We started well enough but then two mistakes give them a 2-0 lead going into the second half and it was an uphill task.
"It was a frustrating game because they kept the ball so well in the second half that we couldn't really press them well enough. Being 2-0 up, they didn't really need to score another goal so they just kept it and made us run. That sort of football is hard work.
"We have got to look forward now. We have another home game to look forward to and we've got to win that one."
West Ham's defeat at the weekend was just their second in 23 matches dating back to 31 January.
With that enviable record in mind, Noble said the Hammers would not allow their confidence to be dented by one bad day at the office.
"We went to Swansea on Saturday to win the game and I said to the fellas that we only lost because of the mistakes and nothing else. We created the chances but didn't convert them and were a bit unlucky to be honest. They got the luck they needed and the goals they needed to win the game.
"People don't make mistakes on purpose. They were silly mistakes that professionals shouldn't make, but everybody makes them now and then. It's just a case of not making too many of them, but we made two in one game and they got punished.
"We're not used to losing games after last season, so it hurts that little bit more. We need to pick ourselves up, forget about it and look forward to the next one."
One plus point at Swansea was the sight of Matt Jarvis in a West Ham shirt. Noble believes the Hammers' new No7 will add a new dimension to the team over the course of the Barclays Premier League campaign.
"He has got loads of quality. His crossing is brilliant and he has got loads of pace, so he's going to be a massive asset to us. Obviously we didn't have that much of the ball on Saturday so he was defending a lot of the time.
"Hopefully when we play other teams and different styles of opponents he can get into the game a bit more and show everybody the ability that he has got. He is a top quality player and we can get him the ball more in future games and he can show the quality that he possesses."
Jarvis and Noble will both expect to feature against Martin Jol's Fulham on Saturday. Having beaten Aston Villa 1-0 in their opening home game of the season, Noble said the Hammers would be going all out to make it six points from six at the Boleyn Ground.
"We will go into it like we did the last home game. We'll be positive because we're at home. We obviously won our last game at home so we'll go into it with confidence. We've got to go and put pressure on them and win the game.
"They have got some good players and have had some good results but we're looking forward to it now."
