A 4-1 drubbing of Aston Villa on Sunday displayed David Moyes' side at their very best as they sit fourth in the Premier League.
The happy Hammers have a 100 per cent record in their Europa League group and are also through to the quarter-finals of the Carabao Cup.
The incredible team spirit in the camp is evident in every game they plan, and fans are loving life under Moyes.
The Scottish coach's appointment and later return to the club was the cause of groans from supporters in the past, but now they could not be happier with their team enjoying a rich vein of form.
And Moyes can take a lot of credit for turning things around at West Ham, according to Jamie O'Hara.
He told the talkSPORT Breakfast: "They are absolutely flying. What a result. They are just so exciting, all of them, the way they are playing as a team and fighting for each other.
"The structure of the club and the set up - everything about them is bang on. That is down to David Moyes, he's saved that football club. Long may it continue for them."
Last season, the Hammers were challenging for a top four place in the Premier League - eventually finishing sixth - and look set to do the same this campaign.
O'Hara added that West Ham can now claim to be the second best side in London, behind only European champions Chelsea and 'miles better' than Arsenal and Tottenham.
He said: "They could get fourth. They are sitting in fourth now and after 10 games the table starts to take shape.
"What I love about [Craig] Dawson and [Mark] Noble is they are still part of it. They've had to bring in another centre-half, and [Kurt] Zouma is a great signing, I don't know why Spurs didn't try to sign him, but they aren't sulking.
"A proper gang, yeah.
"They absolutely are the second best team in London. They are better than Tottenham by a million miles and they are better than Arsenal.
"They are a complete side. For West Ham want to be, they are not going to be Man City - we know that - but, for where they are as a football club, it is the perfect place for them to be.
"They are absolutely on fire."
