Sam Allardyce was left revelling in his side's newfound clinical edge, after battling to a 2-0 Barclays Premier League victory over Wigan Athletic.
Though the Hammers had to be patient against a Latics side renowned for their possession football, Matt Jarvis' 21st minute opener and Kevin Nolan's late second proved plenty to earn Big Sam's men yet another home win.
Perhaps not the prettiest, the three points were still hugely satisfying for the Hammers boss, who insists his team are learning how to win, even when they're not at their fluent best.
He told West Ham TV: "I've been talking about that need for clinical finishing for a number of weeks prior to this run we've been on. I think that the quality of our finishing has gone up to such a level now, that we've become a team that can play well and win, and play not so well and still win.
"We didn't play well, particularly in possession, against Wigan but we've won the game 2-0. Wigan kept the ball an awful lot, so we knew we'd have to defend deep and in numbers, because they're very adventurous in what they do.
"But what it did do is leave them so weak defensively and my disappointment is that had we passed the ball a little better in a counter-attacking situation, we'd have created a lot more than we actually did, but we've created enough because we won 2-0."
It was Jarvis who got the ball rolling with only his second West Ham goal and Big Sam was in no doubt whatesover of the critical part that the winger plays.
"Matt has been outstanding. He has the best crossing stats in the Premier League and not in just terms of quantity but the regular quality. So it shows what a valuable player he has been for us this season. It was a massive move for him, because it was a reasonable size fee for him, not a big one. He has to live with that a little bit and find his way in and now he has come to life for me.
"The good thing is that Matt Jarvis gives our players a rest, because when he gets it, he's going to turn and run at opposition defenders. He's going to run to the opposition's box, do his tricks and nine times out of ten he's going to produce a cross. It's a huge, huge asset for us, when you've got a player who can hang onto the ball as long as he can."
It was left to skipper Kevin Nolan to make it safe with a spectacular volley, one that chalked up his 100th career goal and seventh of the campaign.
"What a blistering start Kevin had to this season. In goal terms he scored five in the first ten. He scored at Fulham which put him on 99 and he has had to wait until now to get his 100th, which has preyed on his mind a little bit, which has been a shame for him and us. Because of that start, I'd have expected him to get about 12 for us this season. He has got that one out the way now and let's hope he can bag a few more in the last four.
"He reads and feeds off Andy Carroll brilliantly. He gets on the move and anticipates where Andy might actually drop the ball, which he did, and then the technique is there for all to see. It was outstanding technique in front of goal, which is the hardest place to produce technique, in the opposition's penalty area. Great finish."
The three points takes the Hammers to 42, and, just as importantly, up to tenth in the Barclays Premier League and Big Sam sees no reason why his side can't continue in this vein until the season's end.
"We've got to make sure we continue this fantastic run of performances and results at home. In actual fact, this was one of our worst performances at home all season, but we've still won 2-0. That says something about the character. We've only lost four in the entire season at home. The fans have got to remember that this is our first season back in the Barclays Premier League."
