Maurizio Sarri has endured a tough debut season at Chelsea.
After a promising start to life at Stamford Bridge, the Italian hit a poor patch of form and seemed to struggle for answers to his team's problems.
That left fans wondering whether he was the right fit for the Blues amid rumours that he had been called in for crisis talks with the club's top brass.
Chelsea have found Premier League success in recent years under Jose Mourinho and most recently Antonio Conte, playing tactically savvy and resilient football.
In fact, their greatest triumph came in 2014 as they won the Champions League by soaking up the pressure and upsetting the odds. Maurizio Sarri's brand of football, dubbed 'Sarri-ball', is the antithesis of such an approach.
He wants to keep possession and play fast, open, attacking football, rather than digging deep with a solid defence to hit teams on the counter.
By contrast, Atletico Madrid boss Diego Simeone has long been linked with a switch to west London due to his similarities with the most successful head coaches in Chelsea's recent history.
The Argentinian is another manager who values a strong defence, demands total commitment from his players to suffer for the cause and is iron-willed in his determination.
In his own words, he is someone who is able to adapt and 'empower' the players who he is working with, and fans looking for a change in the Chelsea dugout may be impressed by how he describes his beliefs and methods.
"You've always heard me say this, the criticism is part of this profession, the opinion too,” Simeone told Goal.com. “What I'm trying to say is that within the styles, first, there's something clear: the style is given by the players on the roster.

“I do not have a style to go to a smaller team and practice my supposed style, I have to adapt to the club that hires me, empower those players and as an employee, make the club grow.
“That is to be a good coach for me. He who brings a style to a club that can't carry it out, he is not a good manager, because he is attacking the club that hires him.”
This could not be more different to Sarri's philosophy, which for all intents and purposes has held back some individuals this season.
