Wolves missed the chance to extend their unbeaten run to five games as they lost 1-0 to Leicester at the King Power Stadium.
Jamie Vardy's 15th minute penalty was enough to give Brendan Rodgers' side the three points after VAR penalised Max Kilman for a contentious handball.
Vardy was given the chance to double his tally from 12 yards just before half-time after Rayan Ait-Nouri clattered James Justin in the area, but the former England international was this time denied by Rui Patricio.
Despite the controversy of the first penalty award, it was the Foxes who had the better chances and were ultimately worthy winners against a drab Wolves side.
Negative Wolves struggle to create
After an impressive performance against Crystal Palace in which Wolves scored two first-half goals, there was added optimism around Molineux that Nuno's side could trouble a Leicester defence that was missing Caglar Soyuncu, Ricardo Pereira and Timothy Castagne.
Instead, Wolves were camped into their own half for almost the entirety of the first 45 minutes. For most of the opening period two gold shirts seemed incapable of completing a pass to each other, while their expected goals (xG) for the half registered at 0.01.
As usual, there was improvement from Wolves in the second half but just two clear chances, from Ruben Neves and Leander Dendoncker, came their way. Raul Jimenez was often isolated while neither Neto, Podence or Traore created too many chances.
Against teams such as Leicester, Wolves must learn that winning ugly is not always possible and they must learn to create chances before the 60-minute mark.
Ait-Nouri's performance brings up wing-back dilemma
Despite a superb debut in last week's win against Crystal Palace, Rayan Ait-Nouri endured a polar opposite performance in his second outing in gold and black.
The France U21 international regularly gave away possession and was given a torrid afternoon by Dennis Praet on the right-wing.
Ait-Nouri's misery was compounded when he foolishly hacked down James Justin in the area to give away a second penalty, but Patricio spared his blushes by stopping Vardy's spot-kick.
After being replaced Marcal in the latter stages of the game, questions will be raised about Ait-Nouri's youthful exuberance possibly costing Wolves in games against similarly matched teams. With Southampton coming up after the international break, Nuno has a decision to make at left wing-back, which has proven to be a problem position since Jonny's injury.
Patricio becomes Wolves' Mr. Reliable
Since arriving at Molineux almost two-and-a-half years ago, the number of errors made by Rui Patricio can be counted on one hand.
Patricio has cemented his status as one of Wolves' best ever keepers with some superb performances in recent years, and kept up an impressive stat at the King Power. The Portuguese number one has saved three of the last six Premier League he has faced, having denied Paul Pogba and Raheem Sterling before stopping Jamie Vardy's second penalty.
Since his mistake cost Wolves two points against Newcastle a fortnight ago, Patricio has been faultless and is undoubtedly one of Wolves' key men.
