Ronald Koeman has been sacked as head coach of Barcelona following a poor start to the club's first season without Lionel Messi in 17 years.
Financial difficulties saw the six-time Ballon d'Or winner leave for Paris Saint-Germain and, in his absence, Koeman's side have struggled.
The Dutchman replaced Quique Setien at Camp Nou in August 2020 and led Barca to Copa del Rey success in his first season, although they finished third in LaLiga and suffered a Champions League last-16 exit, as well as losing the Supercopa de Espana final to Athletic Bilbao.
A shock 1-0 loss at Rayo Vallecano on Wednesday was the final straw and with the club in turmoil, it is imperative that Koeman's successor is chosen with great care.
Stats Perform takes a look at the leading contenders who have been linked with the position.
Xavi
With Koeman dismissed, Barcelona could turn to another club legend in Xavi, hoping the La Masia graduate can succeed where his predecessor failed with an unbalanced squad of ageing regulars and young talent.
The former Spain international has presided over Qatari side Al Sadd since his retirement in 2019, leading them to a league title and six domestic cups.
Turning to a young coach who does not have any experience in Europe amid a time of upheaval could be viewed as a huge risk, however.
Plus, will Xavi see this as the right time to return? The opportunity to manage Barca is likely to come around again at some stage.
Andrea Pirlo
Another candidate who enjoyed a glittering career as a central midfielder in his playing days, Pirlo replaced Maurizio Sarri at Juventus in August 2020 and won the Coppa Italia and the Supercoppa Italiana, but was sacked at the end of his debut season following a fourth-placed Serie A finish and another disappointing European exit, this time against Porto.
While Pirlo has experience of coaching in a top-five league, his stint in Turin hardly demonstrated the Italian has the credentials at this stage of his career to rescue an ailing Barcelona side.
Roberto Martinez
Martinez has a greater coaching pedigree, although the highest level he has managed at has come on the international stage with Belgium - a job he still holds.
The 48-year-old guided the Red Devils to a third-place finish at the 2018 World Cup and took them to number one in the FIFA world rankings, though a major trophy continues to elude them.
At club level, however, he has managed Everton and Wigan Athletic in the Premier League, winning the FA Cup but also suffering relegation with the latter, and also Swansea City below the top tier - rather different jobs to the one that faces the newcomer at Barcelona.
Erik ten Hag
Could Barca turn to another Dutchman to try to turn their on-field fortunes around?
Ten Hag has built his reputation at Ajax, having previously worked at Utrecht and Go Ahead Eagles, as well as a stint with Bayern Munich's second string.
He has twice won the Eredivisie title, while he appeared set to reach the Champions League final in 2019, only for Tottenham to produce a stunning comeback in Amsterdam.
Barcelona, who know what it is like to be on the wrong end of a second-leg turnaround in Europe, have well-documented financial problems at the moment, potentially raising an issue if they want to try to lure away a coach under contract elsewhere.
Antonio Conte
Conte is out of work, at least meaning Barca would not have to pay any compensation to appoint him. However, that does not mean the Italian comes cheaply, considering he has a hugely impressive resume.
The former Juve boss made a quick impact at his previous two jobs, having returned to club duties after a spell in charge of the Azzurri.
He won the Premier League title in his first season at Chelsea, during which they produced an impressive 13-game winning streak, then ended Inter's Scudetto wait last term, leading the Nerazzurri to a first championship since 2010.
His San Siro departure amid Inter's financial cutbacks does raise questions over whether he would want to go anywhere near Camp Nou right now, particularly with Manchester United also reportedly interested.
Marcelo Gallardo
A name strongly linked with the post, Gallardo started out his coaching career with Nacional in Uruguay. However, he has been in charge of River Plate - a club he had three stints at during his playing career - since 2014, winning the Copa Libertadores twice among an impressive list of honours at Los Millonarios.
The last Argentinian coach to take the top job at Barca did not last too long: Gerardo Martino had just one season at the helm.
Gallardo would have to cut short his River journey to do so, a move he suggested was not likely after revealing he plans to see out a contract that runs until the end of 2021.
