Nuno Espirito Santo admits Wolves must improve defensively after their 2-0 defeat to Burnley.
The Clarets led within 90 seconds from Conor Coady’s third own goal of the season before Dwight O’Neil fired home the second in the 77th minute.
Wolves were caught napping by O’Neil’s quickly-taken, deep free kick from which Chris Wood’s acutely-angled shot went in off Coady after hitting the post.
“I’m disappointed because we started the game very badly,” said Wolves head coach Nuno.
“We lost concentration and communication and then it became much more difficult for us.
“When you concede a goal so early, the game comes much harder after that.
“It’s clearly something we can avoid, and we must avoid, and something we can be better organised in stopping.
“But this is part of the growing process of the team and shows we have to be switched on throughout the whole game.”
Nuno added: “There are a lot of things we have to look at.
“We must be clinical and produce better. At the start of the second half we caused them danger but need to do it for the whole game and especially look at our defensive organisation.”
Wolves had 65 per cent of possession but only forced one effort on target, Jonny Castro Otto’s header from Joao Moutinho’s cross which forced a simple falling save from Tom Heaton.
Ivan Cavaleiro and Diogo Jota both fired off target in the second half as Wolves pressed for a reply.
O’Neil punished Wolves with a left-foot drive into the bottom corner that left Rui Patricio rooted to the spot as Romain Saiss was dummied and backed off the youngster after the ball was headed to him from Willy Boly’s clearance to Jota.
Nuno admitted there was no way back after that.
“After we fell behind, we took a little while to settle down again, but we were able to play,” added the Molineux boss.
“In the second half we started very well, we had some chances, we produced opportunities, but we didn’t score.
“When we’re not clinical enough to level the score, and then try to go for the win, it’s difficult, and after the second goal it was ‘game over’.”
“Sometimes you have a lot of the ball and you cannot produce enough.
“I think we produced, we created some good movements, good football, we managed possession well and had clear chances.
“But what disappointed us is the way we started the game, losing 1-0, as it’s not the way we should compete.”
