Matt Jarvis said the West Ham United squad are absolutely determined to put things right after Saturday's disappointing 1-0 home Barclays Premier League defeat by Stoke City.
The Hammers produced an uncharacteristic performance at the Boleyn Ground, lacking the usual intensity and tempo that they have shown on home turf since Sam Allardyce took charge in summer 2011.
That performance was punished by Jermaine Pennant's 82nd-minute free-kick, which condemned West Ham to just their second home defeat of 2013 and left the England winger feeling that they had let themselves and the supporters down.
"I was very disappointed with the performance and the result, really, especially with it being at home where we have such a good record," Jarvis told West Ham TV. "We're going to have to sort it out and make sure it never happens again and get back to winning ways and what we normally do at home.
"Stoke did play well but we didn't play our usual high-tempo game, especially at home where we're normally very good. It just didn't happen on Saturday."
Jarvis and his team-mates have redoubled their efforts at Chadwell Heath this week in a bid to ensure they are ready when they resume Barclays Premier League hostlities at Southampton on Sunday 15 September.
Before then, the Hammers will travel to Spain to take on Primera Division RCD Espanyol at the Estadi Cornellà-El Prat on Thursday evening in a fixture aimed at ensuring they retain match-sharpness during the international break.
"We will make sure we work really hard, as we usually do at the training ground, and will get our tactics spot-on as we normally do and will focus strongly on that game and getting a very positive result.
"We felt the extreme disappointment exactly the same as the supporters after the Stoke game and we're going to make sure we turn it around and make sure that never happens again at home.
"It would be nice if there wasn't an international break and we could get straight back into a proper Premier League game, but it gives us something to use to get us ready for the Southampton game.
"It won't be an easy game at all. Southampton have signed quite a few players so it'll be tough, but we got a draw down there last year and we beat them at home, so hopefully we can take a positive result."
Following the trip to St Mary's, West Ham return to home turf for two important matches, hosting Everton in the Barclays Premier League on Saturday 21 September and Cardiff City on Tuesday 24 September.
"The main thing is that we've got to get back to winning ways and making the Boleyn Ground a fortress, as we did last year."
