Nuno Espirito Santo insisted he must find the cause of Wolves’ slow start despite their Europa League victory at Slovan Bratislava.
Raul Jimenez’s second-half penalty, five minutes after Romain Saiss’ leveller, earned the visitors a 2-1 comeback win in Slovakia.
“Everybody is happy, the first half was not so good but the second half was a very, very good performance,” said boss Nuno, with Wolves a point behind group leaders Braga.
“It’s something that we have to analyse, why we required so much effort in the second half.
“In the first half we didn’t play so well, we conceded a goal and we cannot do that.”
Nuno added: “We didn’t expect to play in a stadium like this but the message was clear.
“The children enjoyed themselves because some people did something wrong so I think that sends a good message out. It was a good environment.”
It was a deserved opener for the hosts but the visitors improved following Adama Traore’s introduction at the break.
Goalkeeper Dominik Greif failed to stop Saiss’ 30-yard drive from finding the corner in the 58th minute and Wolves won it when Jimenez scored from the spot after he was pushed by Vernon De Marco.
Nuno added: “He was frustrated, two or three minutes before the ball was out and it was our ball, the referee was clear and Slovan didn’t respect that, so that took him out of concentration and he made a mistake.
“We know how it goes. Don’t do it again.”
“Of course I am disappointed because this was a game where we deserved a better result,” he said.
“We made some mistakes and big clubs punish mistakes like that, Wolves did that with two goals.
“At half-time they made some tactical changes and unfortunately we made some mistakes and were punished.
“We can still challenge for the first two spots, we want to take as many points as possible in the group.”
