West Ham manager Sam Allardyce wants his side to be more clinical in front of goal after they relied on a penalty to beat Peterborough at Upton Park.
Skipper Mark Noble converted the spot-kick after 11 minutes, but the Hammers failed to make the most of their good start, rarely threatening Paul Jones again in the Posh goal.
Allardyce, although happy with the win, admits he was disappointed that his players failed to convert pressure into chances.
"I'm satisfied with the result of course and delighted with the clean sheet and delighted with the three points but just not too happy with our finishing today," said Allardyce.
"We have had to rely on a penalty to win us the game today and that is the only disappointment, everything else went to plan.
"We keep scoring lots of goals playing 4-3-3. You only have to look at the match stats and look at how many times we got in their box and crossed the ball. We just didn't hit the target enough or work their keeper enough.
"(There were) no jittery nerves at the end and we saw the game out. It is an important three points for us and pops us up to fourth.
"The overall scenario is that this league doesn't finish its chances as well as the Premier League and that is probably one of the biggest differences."
Meanwhile Peterborough manager Darren Ferguson felt his side missed a glorious opportunity to pick up a precious point on the road.
"Most people coming here today would have thought it would have been a comfortable game, I always knew we would have a chance because we have a team that can pass the ball." said Ferguson.
"I really feel it is a lost opportunity to get something out of the game and we have had too many of them and it is getting quite annoying - I'm fed up of people saying 'well played and unlucky', I'm only interested in winning games and we need to have that mentality from the start."
Ferguson also confirmed that he fears the worst after Lee Tomlin suffered a knee injury during the game.
"It has swollen up straight away which suggests it is ligaments," added the 39-year-old.
"I fear the worst for the boy because it could be a bad one but you never know. We will scan him tomorrow and if that is the case it is disappointing for the lad really."
