Joey O'Brien admits the Hammers are close to surpassing the targets they set out at the beginning of the 2012/13 Barclays Premier League campaign and believes the wealth of experience in the dressing room has been keen to their success.
Saturday's 2-0 victory over Wigan Athletic took the Hammers over the 40-point mark and back into the top half of the table and with a trip to Manchester City next on the agenda, O'Brien is looking for another strong display.
"We've had a fair few clean sheets this season," O'Brien told West Ham TV.. "The manager had set us a target for the season and I think we're nearly there. If we can pick up one or two more over the next few weeks then it will have been a decent season for the back four.
"At the start of the season a top ten finish was always the target. There wasn't any talk of relegation when we set out in pre-season and look at us now, we're right on track to finish in the top half of the table.
"As a newly promoted team that's a fantastic achievement. Although Reading won the Championship last season, they've struggled this year. It's a hard league but we had players who had played in the top flight and that helped us from the start.
"Playing left back is something different but I've been playing there for a while and it's grand. It makes no difference to me whether I play right back or left back, I just enjoy going out and playing and hopefully I can stay in the team now until the end of the season.
"We've been really good at home this season, I think we've only lost four and they've been against the big teams. We've played really well here. Last season really got us in good stead. We had a few dodgy moments in the Championship last year. I think that experience from last season has helped us turn the Boleyn Ground into a real fortress."
Looking back at Saturday's visit of Wigan Athletic, O'Brien believes the Latics do deserve some credit for their display.
"They're a good side and they keep the ball a lot and create chances, but we defended well at the end of the day all that matters is winning," O'Brien recalled.
"They're in their position because they're not winning as many games and we're in a good position because we've won games.
"We had watched a lot of videos and most of the time they have a lot of chances and have a lot of the ball. The formation they play is slightly different to what we're normally used to and it creates a few problems. The scoreline is all that matters and we kept a clean sheet and scored two goals."
The Republic of Ireland international added to the praise for skipper Kevin Nolan, who netted his 100th career goal against Wigan on Saturday, to help the Hammers record the important 2-0 victory.
"Fantastic," he added. "He's been doing it all of his career, 100 goals is a really good record as an English midfielder to get that many goals.
"Kevin gets the important ones, when it matters. Look at our game against Wigan, we needed that cushion and he popped up again.
"It did get nervy at times but we've done this a few times this season when we've just dug in and in the end we come out the other side of it. That's what the lads were saying on the pitch and then Nobby popped up with that goal to ease everyone's nerves and give us a comfortable win."
