The Carabao Cup final was a tense affair as two of the Premier League’s best teams battled it out for the first available major trophy of the season.
The crazy act of defiance – something many have never seen take place before – generated a lot of controversy and debate throughout the footballing world.
But incredibly this isn’t the first time a similar act of rebellion has taken place.
Here are five other occasions when a player has overruled the authority of their boss and refused to be substitued.

1. Lionel Messi
Without a doubt, the “little magician” is one of the best to ever play the game.
His class and unbelievable technical ability mean he is capable of changing any game at any time, so it’s easy to see why he would want to always be on the pitch.
But during a league fixture at home to Eibar in 2014 the Argentine took it upon himself to decide how long he was going to play.
When Munir looked set to replace Messi the star gave his then manager Luis Enrique a thumbs up suggesting that he would continue playing, despite his side being three goals to the good and looking certain to win.

Not wanting to upset his superstar, Enrique withdrew Neymar instead.
The boss later told the press: “I have to take everything into account, but I trust in how he feels and what he tells me.”
2. Nikola Kalinic
Croatia’s World cup campaign last summer was a magnificent effort that saw them advance all the way to the final and resulted in the squad and staff being showered in glory when returning from Russia.
However, forward Nikola Kalinic was sent home in shame during the group stage as he was accused by his manager Zlatko Dalic to have refused to come on as a substitute as he ruled himself not fit to play.

His boss disagreed with his verdict and hinted there had been similar incidents prior to this one that meant this was the final straw for Kalinic.
He hasn’t represented his country since his early World Cup departure.
3. Carlos Tevez
Back in 2011, during a game away at Bayern Munich in the Champions League, Manchester City boss Roberto Mancini called on experienced striker Carlos Tevez to find an all-important goal for his side.
But Tevez never made it onto the pitch and instead was accused of refusing to leave the bench. Tevez denied the claims and blamed his actions on a misunderstanding.

The arguments went back and forth while Tevez remained out of selection for the squad for five months and was also fined a hefty figure.
He was eventually reintroduced towards the end of the campaign, which finished with Tevez playing an important role in Manchester City securing the Premier League title.
4. Lukasz Fabianski
When playing for Swansea in 2017 Lukasz Fabianski was involved in a collision late on against Tottenham and looked like he might not be able to walk off the pitch.
After several minutes of medical attention the keeper rose to his feet insisting he was fine to continue. Further play showed Fabianski was still feeling the consequences of the knock and Swans manager Paul Clement had a substitute readied.
The change was signalled for by the fourth official but the Polish keeper refused to make way. Continued remonstrations left Clement with no choice but to cancel the swap and play resmued.
Proceedings didn’t end there, with a late collapse turning what looked like a 1-0 win into a 3-1 defeat in the space of five minutes.
5. Les Sealey
Ex-Manchester United goalkeeper once refused to leave the field of play during a League Cup final – exactly like Kepa did.
However, Sealey was praised for his actions that were then seen as heroic.
The keeper had suffered a badly gashed knee, which left him in no condition to play on with twelve minutes remaining.
But United had no reserve keeper available, so the 1990 FA Cup winner decided to continue playing instead of making an outfielder glove-up.
Amazingly, Sealey finished the match but it ended in defeat for United as Sheffield Wednesday lifted the trophy with a goal from John Sheridan.
