John Carew insists he and his West Ham United team-mates will be working hard to eradicate the mistakes that caused Tuesday's 1-0 npower Championship defeat by Ipswich Town.
The Hammers were not at their fluent best against the Tractor Boys, but looked like gaining a goalless draw before a series of defensive errors allowed Lee Bowyer to fire in an 89th-minute winner.
The goal represented the fourth time this season that West Ham have conceded in the final stages of a match - a record that has cost them four league points and their place in the Carling Cup.
On the attacking front, the Hammers did not create the clear-cut chances they would have hoped at the Boleyn Ground, being largely reduced to long-range efforts and hopeful crosses into the Ipswich penalty area.
Experienced striker Carew said the squad, who returned to training on Wednesday morning, were determined to put things right.
"We conceded a goal in the last minute again, as we've done too many times already this season, so we're very disappointed.
"We were hoping to create more at home. We're always aiming to create more chances and stuff, but we obviously couldn't so I'm sure we'll sit down and talk about it to work out what went wrong.
"We also need to work on not conceding goals in the last minute. The manager is not happy about that - nobody is."
Carew will hope to make his first league start for the club at Crystal Palace on Saturday - a fixture that could see him face Norway team-mates Steffen Iversen and Jonathan Parr.
Striker Iversen, 34, has partnered Carew regularly at international level, with both being part of Norway's squad at the 2000 UEFA European Championship finals, while 22-year-old winger Parr has been a revelation since joining the Eagles from Aalesund in July 2011.
While he will enjoy meeting his compatriots, West Ham's No11 said he will be focusing all of his efforts on ensuring his side leave Selhurst Park with a victory.
"We just have to get over this disappointment and we will start to think about the next game from Wednesday morning.
"It will be nice to see Steffen and Jonathan again, but I am not thinking of them right now."
