The visitors had made a promising start at Molineux, with early chances for Rhian Brewster and James McAtee. But Pablo Sarabia’s header exposed more poor defending from Sheffield United and the frustration was plain to see as centre-back Robinson and midfielder Souza exchanged words and shoved each other soon after the goal.

VAR decided the incident did not meet the threshold for violent conduct for a red card, which would have been a relief for a side that saw Mason Holgate dismissed in the first half against Brighton last weekend.

But rather than implode, Sheffield United regathered their composure and had the better of the opportunities in the second half, with McAtee shooting wide, Brewster testing Jose Sa and the ball bouncing agonisingly through the six-yard box in the final moments when no player in red and white could apply the finishing touch.

The Wolves supporters grew increasingly agitated by the performance of their own players in that second 45 but Gary O’Neil’s team held on for a third win in four Premier League games, which moves them up to eighth and keeps their dream of European qualification alive. Sheffield United stay bottom, eight points from safety.
