Nuno Espirito Santo was bitterly disappointed with Wolves' performance against Watford on Wednesday.
Wolves were downed by the Hornets in a 2-1 defeat at Vicarage Road.
"I'm not happy," said Nuno.
"Of course, I'm not happy. I think we should do better.
"It was a tough game. In the first half, we had a couple of good chances.
"But we didn't have enough rhythm with the ball and reaction to the second ball.
"The goals of Watford come from our mistakes in possession, so it's something we have to look at.
"We improved a little bit in the second half, but not enough."
