The Hammers defender stresses that the side must find a way to stop conceding late goals if they are to build upon a successful season.
West Ham United's push for European qualification has faltered somewhat in recent weeks with four consecutive draws, and defender Winston Reid has told the London Evening Standard that they must find a way to stop conceding late goals if they are to push on.
The Hammers were pegged back to a 2-2 draw by Leicester City on Sunday after conceding an injury-time penalty, meaning that they have now conceded a costly goal in the last 20 minutes of each of their last four matches.
The week before, Laurent Koscielny equalised for Arsenal 20 minutes from time to hold Slaven Bilic's side to a 3-3 draw, and they also conceded 75th-minute and 89th-minute levellers from Crystal Palace striker Dwight Gayle and Chelsea's Cesc Fabregas respectively.
That has led to a stutter in form which has left the Irons seven points off a Champions League spot with five matches remaining, and Reid has urged his side to remedy the problem which is threatening their European qualification for next season.
The New Zealand international told the Standard: "We need to learn from our mistakes. If we look back at recent matches, it started in the first FA Cup tie at Manchester United where we conceded a late goal.
"The same thing happened at Chelsea, Crystal Palace and Arsenal — and again on Sunday at Leicester. We have a young squad and we have to learn from this experience. We want to build upon this season and learn from the mistakes we have made collectively.
"It’s not good enough that we have made these mistakes and as a group, we have to learn. We need to understand what we have done incorrectly."
Reid's side take on Watford at Upton Park on Wednesday night as they look to secure a first win in six matches in all competitions since their dramatic turnaround against Everton at Goodison Park on 5 March.
