Leeds United and Aston Villa ended the match in a 1-1 draw, after a very tight match that had a red card and plenty of other drama, with the result sending Leeds to the playoffs, whilst Sheffield United were automatically promoted to Premier League.
Villa player Jonathan Kodjia was laying down injured in the middle of the pitch, and practically the whole Villa team was ordering the Leeds player to put the ball out of play, but Mateusz Klich opted not to do so, as he put the ball past Jed Steer, opening the scoring.
However, that goal sparked a mass melee, with several blows being flown in the brawl, which eventually led to Villa defender, Anwar El Ghazi to be sent off, with stewards having to be called onto the pitch to try and stop the ongoing fight.
Right after the goal, Leeds manager Marcelo Bielsa was given an earful of words from the Aston Villa assistant manager, John Terry, with the Argentine then agreeing with most of his players to let the Villa players walk the ball right into the net after kick-off.
Most of the Leeds players agreed to do so, and Albert Adomah slotted the ball into the empty net, yet an enraged Pontus Jansson made a wholehearted attempt to try and prevent the goal, sparking even more on-field conflicts.
However, the game soon died down, with Leeds being destined for the playoffs, which meant that Sheffield United were officially promoted to the Premier League from the EFL Championship, with next season being their first in the top-flight since 2006/07, when they were relegated on the final day by just a single goal.
Bielsa afterwards said that "English football is known for sportsmanship so I don't have to comment, it's common in England."
This unusual turn of events sparked a flurry of praise directed towards the Argentine on social media, with this being deemed "one of the best acts of fair-play" in a long time.
