Wolves midfielder Mario Lemina has admitted frustration after defeat at home to West Ham.
Lemina concedes Wolves were poor in the second-half on Saturday.
He said, "I'm really disappointed with our second half. We were fantastic in the first half and the way we didn't control the second half, we are really disappointed with it.
"We could be better. We showed it in the first half.
"Of course, I would have been happy with the disallowed goal because a draw with West Ham would be good for us to continue to fight for what we aim for.
"We need to work, continue to show character and personality and control the second half better. We are at home and we didn't control it, which I didn't like.
"We need to be honest with ourselves. It's not possible to play like that in the first half, maybe even the best first half we've played, and the second half is not acceptable for us as a group."
Lemina added: "The gaffer told us they would be aggressive, but if we show character we would try to play and find the space behind them.
"With the clever players we have like Sarabia and Cunha, we didn't do anything like that. We didn't play in the right way."
He added: "If we want to stay where we are and play for something better for the fans, to show them we compete at the top of the league.
"We cannot play a first half like that against a really top team and show a really bad second half."
