Wolves boss Nuno refused to criticise VAR after defeat to Aston Villa.
Substitute Anwar El Ghazi converted a stoppage-time penalty as Villa snatched victory in their West Midlands derby at Wolves.
Wolves had the better of their first home game since striker Raul Jimenez suffered a fractured skull, with Fabio Silva hitting a post midway through the second half.
Villa goalkeeper Emiliano Martinez then denied Leander Dendoncker, before the visitors had midfielder Douglas Luiz sent off after picking up a second booking late on.
But Nelson Semedo brought down John McGinn in injury-time, handing El Ghazi the chance to sidefoot home from the spot.
There was still time for the hosts to have midfielder Joao Moutinho dismissed for a second yellow card.
Nuno later said: "It is always disappointing to lose. We played good. I didn't see the images (for the penalty). The referee judged and the VAR saw it. We keep on going. In the first half it was an intense game and both teams were tight. In the second we controlled the game and had clear chances. We try to keep on growing on these aspects and be more clinical. Too many fouls in the first half. It did not flow. In the second it was better.
On Fabio Silva, he added: "He worked well. He was linking with team-mates and had good chances. He worked hard. The idea to make a player grow is to help him and give him competition."
On scoring goals without Raul Jimenez, Nuno concluded: "It is something we have to do as a team - fine solutions."
