Vitor Pereira has emerged as a potential candidate to replace Marco Silva as the new Everton manager.
The 51-year-old is being considered for the role along with Carlo Ancelotti, David Moyes and Rafa Benitez after Silva was sacked following the Toffees' humiliating defeat in Wednesday's Merseyside derby.
But who exactly is Pereira and why is he being considered for the role? Here, Sportsmail answers the main questions on Everton supporters' lips.
Compared to others being linked with the job, Pereira's CV doesn't quite stand up but he has enjoyed success at the majority of clubs he's managed.
Pereira got his big break after being named as Andre Villas-Boas' assistant at Porto in 2010. He helped Villas-Boas wrap up the Europa League title in 2011 before being given the manager's role on a full-time basis after Villas-Boas departed for Stamford Bridge.
Having enjoyed three trophy-laden years in Portugal, Pereira made the strange career choice of making the switch to the Saudi Professional League after signing a two-year deal with Al-Ahli SC.
While he didn't enjoy the greatest of success in the Middle East, a move back to Europe materialised after he was offered the job at Olympiacos.
Pereira was at the Greek club for less than six months but still managed to win 60 per cent of his games there, picking up more silverware along the way.
Two days after his contract was mutually terminated at Olympiacos, he signed for Fenerbahce in Turkey but, once again, it didn't last long.
The one black mark against his name came when he oversaw 1860 Munich's relegation to Germany's third tier in 2017.
Ugly scenes marred their relegation/promotion play-off clash with Jahn Regensburg after the game to be stopped for 15 minutes due to violent outbreaks and pitch invasions.
Following the lowest point of his managerial career, Pereira would succeed Villas-Boas for a second time after being appointed as the manager of Chinese Super League side Shanghai SIPG, where he has been at for the past two years.
Pereira has never been at a club longer than 24 months, having managed six clubs in six years.
In his first official match as Porto manager, he won the Portuguese Supercup before leading the club to league glory in his first full season in charge.
Pereira then managed to win Premeira Liga again the following season despite coming under heavy criticism for Porto's performance in the Champions League.
Following his stint in Portugal, Pereira would head east across the continent to take charge of Olympiacos, where he would win the Greek cup and the league in the 2014-15 campaign.
At his current role with Shanghai SIPG, Pereira managed to beat Guangzhou Evergrande to the Chinese Super League title while also adding the Chinese Super Cup to his growing haul of silverware.
Pereira's sides after often very attack-minded and has relished using Brazilian duo Hulk and Oscar in a 4-3-3 variant at Shanghai SIPG.
A few years ago, Pereira insisted that his sides must play a distinct style of football while pressing his opponents high up the field.
He said: 'I like my teams to have total control, of the ball, of the game. I like to see my teams pressing very aggressively, very high up the pitch.
'The important thing is the balance between the attacking and defensive elements, but pressing high is the best way to defend. We have had the best defence in Portugal for the last two years.'
Pereira has a particular advantage over other candidates as he met with members of Everton's board six years ago when they were seeking a replacement for David Moyes, and was said to have impressed them with his knowledge of the game.
Everton ended up appointing Roberto Martinez, while Pereira, who was at Porto at the time and had just won the Portuguese top-flight, moved on to Al-Ahli in the Saudi Pro League.
While he remains one of the highest-paid coaches in the world, the Toffees believe his attack-minded football and track record all over the world can help get the club back on track.
The Portuguese tactician was a midfielder back in his day but only played at an amateur level before retiring at the age of 28.
