Winston Reid has told West Ham United's official website that he has become frustrated with the side's tendency to concede late goals.
The Hammers have let a number of leads slip towards the end of matches, and Reid admits that is 'extremely disappointing'.
The New Zealand international centre-back feels that recent performances from his side have not done justice to the quality that the Hammers have in their team and insists that the squad still care about where they finish this season.
“Sometimes, especially lately, we haven't been concentrating fully and in the last ten minutes we've been conceding unnecessary amounts of points, which is extremely disappointing," he said.
“Obviously the performances recently have not been reflective of what we are capable of, as we showed in the first half of the season. From the outside, people might think that we're already on holiday, but we've tried to maintain the effort on the training pitch and in games.
“The run we've been on in the past 15 games, we've only gained 12 points from - which, considering where we were before, is not good enough so our season's gone from being fairly high up in the table to a mid-table season.”
There had been talk of a potential European push around the Boleyn Ground after West Ham's blistering start to the season, but those aspirations appear to have been shelved for another year.
The side's form in 2015 has been poor and they now look set to finish in mid-table, which can only be considered a disappointment.
West Ham have shown that they can be a match for the very best on their day, but they have failed to maintain those standards throughout the season and Sam Allardyce has fallen under mounting pressure as a result.
The Hammers' boss's contract expires at the end of the season and it remains unclear whether he will remain at the club past the summer and into 2015/16.
