Spaniard Pablo Sarabia's header in the 30th minute gave coach Gary O'Neill's men three points, raising them to eighth place with 38 points, while Sheffield's score, which suffered its 19th defeat this season, froze at 13 points, and became threatened with relegation 12 stages before the end.

Following the goal, a verbal altercation broke out between the Sheffield United duo, Brazilian midfielder Vinicius Souza and defender Jack Robinson, and the matter developed into a stampede between them.

The match referee resorted to the video assistant referee “VAR” to reveal the truth of what happened, before allowing the two to continue playing, which brought to mind the fight that took place between Newcastle United players Lee Bowyer and Kieron Dyer in 2005, which led to both of them being expelled.

Sheffield coach Chris Wilder denied the importance of what happened on team spirit, saying: “This happens in every club across the country, 3 or 4 times a year.”

He continued: “This is happening behind closed doors at all levels, in Manchester City (the defending champion) and at the bottom of the second division.”

He added: "You don't want to see that but these things happen. The mouse spotted him, for me you just have to move very quickly. They were told of their responsibilities at half-time. We spoke to the two players and they are fine."
