Marcelo Bielsa stunned Italian football on Friday after producing one of the most shocking u-turns you will ever witness.
Bielsa was named the new manager of Lazio just two days ago but has quite incredibly already quit the job.
Yes, that's right, the 60-year-old Argentine will not lead Lazio into the 2016/17 Serie A campaign. The experienced coach often splits opinion, but there's no doubting that he could have made a major impact for Lazio over the coming years.

As it stands, though, no one appears to be quite sure why Bielsa has made the decision - it has been suggested that he could be set to take on the Argentinian national team job for a second time - but it's a bizarre situation nonetheless.
There's every chance that Lazio, who have already reinstated Simone Inzaghi as head coach, could sue the unpredictable manager.
As you can imagine, then, Lazio have released a statement following the strange turn of events and it's safe to say that they are not too happy.
Here's what they stated, as per their official website:
“We note with surprise of the resignation of Mr Marcelo Bielsa, also on behalf of its employees, in clear violation of the commitments undertaken with the contracts signed last week and regularly deposited with the League and the FIGC with their required procedures.
“The Company reserves all actions to protect its rights. Entrusts the management of the team, currently in pre-season training, to Mr Simone Inzaghi.”
We will most definitely keep an eye on how the saga develops over the coming weeks, but you're unlikely to read anything more unusual than this today.
