James Tomkins insists the atmosphere around the Club has completely changed following Sunday's momentous 3-0 win over local rivals Tottenham Hotspur.
Having dropped into the relegation zone ahead of the trip to White Hart Lane, West Ham United sought to halt a run of five Barclays Premier League games without a win.
As it turned out, 13 amazing second-half minutes saw Winston Reid, Ricardo Vaz Te and Ravel Morrison each find the net, spelling an emphatic end to that winless run and, according to the Hammers No5, completely transforming the mood about the place.
He told West Ham TV: "It's amazing what a win can do! Ever since, everyone's come in buzzing from what happened at the weekend and it's certainly an atmosphere that I won't ever forget in my career. A 3-0 win at White Hart Lane, it doesn't get much better than that and long may it continue."
All three West Ham goals were met with wild celebrations from typically vocal away support, who, having waited 14 years since the last White Hart Lane win, made certain of enjoying this one.

Just short of 3,000 Hammers fans could be heard loud and proud right throughout Sunday's epic and Tomkins admitted their unwavering support was vital at a tough time.
"They were brilliant all game and it was a massive result for everyone," he continued. "It came at a time when we were struggling. Well, I say struggling, but we were in the bottom three and people were looking at us thinking we're in a bit of bother, but that's not the case.
"We always stay positive at the Club and we knew it was a massive game for the fans and everyone involved. It was a massive victory."
Having twice captained the Hammers in the Capital One Cup this term, Tomkins is now enjoying an extended run at the heart of Sam Allardyce's defence in the Premier League too.
The stylish defender was once again on top of his game against Spurs and believes the team's fortunes have finally changed for the better.
"I think Hull was an unlucky result for us in the end, with an undeserved penalty going against us," he explained. "On another day they're never given.
"The luck went the other way on Sunday with Vaz's goal coming off his thigh and I think we needed that bit of luck against a team like Spurs.
"We got a great result at the end of the day and I'm still pinching myself that we've beaten Tottenham 3-0 at White Hart Lane, so we're still buzzing over that and we can take that confidence into our next match."
That next match sees title-challenging Manchester City visit the Boleyn Ground on Saturday 19 October, with Tomkins hopeful that he and his team-mates can spring another surprise.
"Manchester City's another big game for us and we're all confident we can get something out of it now."
