West Ham United manager Gianfranco Zola has warned his side that they cannot afford to repeat the poor second-half performance given in the 2-2 draw at Sunderland.
The Irons led 2-0 at the Stadium of Light, but threw the lead away despite their hosts being reduced to ten men by the sending-off of striker Kenwyne Jones right on half-time.
Zola told the club's official website:"It's not possible for the team to play like it did in the first half and then we let them in as we did.
"That's something that we have to correct because it's keeping us in a position in which we don't deserve to be.
"When you are in a position where you are in control against a team that it is one man down you have to keep it that way, no matter what.
"I believe that in the second half, the atmosphere and their willingness and desire to come back impressed us and we didn't play.
"We didn't play in the second half, we didn't play. Otherwise the game would've finished with a different result. It could have been much more than two goals and I'm upset about that.
"It's a pity to see a team play like we did in the first half and not get a victory.
"I have mixed feelings because it's not the first time we've played like that. In recent weeks we've been playing really good football and, really, it's a pity because we should have more points than we've got."
