Wolves boss Bruno Lage admits they're under pressure after their defeat at West Ham.
Wolves lost 2-0 to drop into the bottom three on Saturday.
Lage said, "Especially in the first 30 minutes we controlled the game. We controlled the game with the ball. In the first 30 minutes we had three good chances.
"In the second half we tried to bring more energy and be more aggressive in the final third. I don't have doubts we are a different team with a striker in front of us. We had good chances. Diego Costa had good chances.
"For the chances we had and West Ham had, we don't deserve that [to lose]. But it happened and we need to move on.
"Lukasz Fabianski did a fantastic job today. Good saves. We're doing that. We need to work. I can say we are a different team when we have a striker. We don't have luck with Sasa Kalajdzic and we need to solve it now with Diego. He can play 35 minutes today. I think he can play a good level.
"We're under pressure."
On his double sub that was unpopular with the fans, Lage continued: "[We were trying] to be more aggressive in the middle and win second ball. To try to open up Adama Traore on the side. Chem Campbell had two or three good situations. I'm very proud of what we did.
"[We will] continue to work. I know the fans support us. We try to do our best for them. We're in a bad moment, we don't have goals or victories. We need to continue to work. I can promise we will work hard every day to bring good games and victories for the team.
"Look, we've played eight games. Look how many we lost when we had a striker in the team."
