Sam Allardyce said his side could take plenty of positives despite going down to defeat at the hands of Premier League leaders Chelsea at Upton Park on Wednesday night.
However, Big Sam also added that some poor finishing was one of the key reasons the Hammers failed to get at least a point, with the Blues now losing just one of their last 18 meetings against the East Londoners.
"I thought we gave a fantastic performance," said Allardyce. "After the disappointment we had recently, we deserved at least a point or maybe even three.
"On the back of the game against Palace and conceding in the dying moments of games against Tottenham and Manchester United, the lads gave a good account of themselves.
We put in a great performance and we could take a lot of positives out of the game.
"We very rarely don't score at home, which is weird scenario after creating so many chances against Chelsea, which is difficult to do because of how good they are, not only offensively but defensively. A little bit of poor finishing and great goalkeeping was the combination in the game which has denied at least a draw for us."
Allardyce added he thought the goal should have been ruled out for offside.
"Kevin Nolan was offside at Old Trafford against Manchester United when we scored for 2-2, there was half an inch of his nose offside, and there was six inches of Hazard's body offside and the goal stood," said the manager.
"It was a good performance and I couldn't have asked for anymore. We just need to keep playing like that on a regular basis and we'll start winning again."
The Hammers went 1-0 down just after a quarter of an hour through an Eden Hazard header, after some neat build up play from Jose Mourinho's men.
However, the Boleyn Ground side had plenty of opportunities to score, with Diafra Sakho, Enner Valencia and Cheikhou Kouyate testing Thibaut Courtois on numerous occasions.
Referee Neil Swarbrick had a night to forget, and quite frankly awarded Chelsea some soft decisions, which included John Terry escaping a second yellow card after blocking Kouyate's run into the box that could have so easily been a goal scoring chance.
Six minutes into the game game, defender Winston Reid was forced off with a hamstring injury and replaced by James Collins.
Big Sam contemplated how the game could have changed if he had more options, for example, being able to bring on an injured Andy Carroll.
Allardyce said: "Ginge [Collins] came on and did a really good job, but were running short of options.
"We had a brilliant game today, but maybe with 20 minutes to go, I wish I would have had Andy Carroll coming off the bench because you think like that as a manager, choosing alternatives as were running out of attacking options with Carlton Cole out as well.
"I can't fault how well we played today and it's rare we don't score a goal here."
As the Hammers are not in action at the weekend due to the FA Cup, they are jetting off to Dubai on Thursday for some warm weather mid-season training.
The London derbies don't stop there, as West Ham are in action against Arsenal at the Emirates stadium in eight days' time.
