Marcelo Bielsa lost his job this weekend after Leeds United fell to another disappointing result on Saturday afternoon.Days after losing 6-0 to Liverpool, they were demolished 4-0 by Tottenham Hotspur at Elland Road.That result left Leeds winless in six games, a run that saw them fall to 16th and just two points above the relegation zone.Thus, Bielsa lost his job and he has since been replaced by American Jesse Marsch.Former Leeds defender Stephen Warnock appeared on Match of the Day 2 on Sunday evening where he discussed Bielsa's demise.He argued that Bielsa was stubborn with his tactics and refused to change them despite a downturn in results.“Everyone says, the definition of insanity is doing the same over and over again and getting the same results – and that’s what it seems to be,” Warnock began, per the Mirror.“You’ve got to change your ways. You’ve got to adapt."Warnock then used the example of Jurgen Klopp. Klopp came to the Premier League using a huge intensity style of football named 'Gegenpressing.'That was a term that Warnock attempted to refer to. However, he had a bit of a shocker as he accidentally said Klopp's Liverpool initially played 'Gangnam Style.'“When Jurgen Klopp came into the Premier League they (Liverpool) played Gangnam Style football, Gangnam Style press..."View the moment below:

'Gangnam Style' is of course a song which was released by South Korean singer Psy in 2012.

The song featured Psy doing a strange dance which became popular all over the world.

Leon Osman, who accompanied Warnock on Match of the Day 2, looked unsure at what he had just heard.

Many football fans found Warnock's slip of the tongue funny and you can view some reaction below...

Of course, it's not a huge mistake by Warnock but it's still an amusing one.

He continued: "He changed the style, changed the system, adapted to it. The best managers in the world adapt.

“It was hugely frustrating because we’re all big fans of Marcelo Bielsa, it’s that personality he’s got.

“He’s brought entertainment to Leeds and their fans but then there’s got to be the entertainment but then you’ve got to deep dig, be organised, be resolute.

“They aren’t – they’re far too easy to play against, far too easy to pass through the middle against.

“The man-for-man system, I think it’s become frustrating for the players as well, because you see centre-halves go past midfielders into centre-forward positions, because they leave gaps for you. It’s too easy to play against.”
