Lionel Messi's days at Barcelona appear to be numbered, with the club captain and talisman heading into the final six months of his contract.
As such, he can begin discussions with other clubs ahead of a potential free transfer once his contract expires on June 30.
Messi, 33, set things in motion back in August when he rocked world football by publicly confirming his desire to leave the only club he has ever represented as a professional, and with whom he has won everything.
Barca's surrender to Real Madrid in LaLiga's title race and the 8-2 thrashing at the hands of Bayern Munich in the Champions League appeared to be the final straw for Messi earlier this year, though the departure of president Josep Maria Bartomeu might have improved the club's chances of keeping him.
Additionally, Joan Laporta is the favourite to succeed Bartomeu in next month's election, but if he cannot persuade Messi to stay then football looks set to see a move that will rank as one of the most seismic in the history of the sport.
So, where could Messi end up next?
Newell's Old Boys
Messi's relationship with the public in Argentina has often been strained due to the fact he moved to Barca at the age of 13 and developed in their famous La Masia academy. But he started out at Newell's five years prior to that and a return to his hometown of Rosario would be an understandable move as he enters the latter stages of his career. Unrealistic? Perhaps, but it's a move all football romanticists would love to see.
While his form this term may have been somewhat disappointing by his usual standards, Messi undoubtedly still has the quality to play at the highest level. City, managed by former Barca boss Pep Guardiola, are said to have been looking into the feasibility of bringing the Argentina superstar to the Etihad Stadium. Media reports have suggested he could spend a few years in Manchester before then being sent to sister club New York City FC in MLS for the final seasons of his career. City are certainly one of a handful of clubs that could match Messi's huge wages, and there is a strong lure given the Blaugrana alumni running the show at City.
PSG have been right at the forefront of this saga since the very start in August. Thomas Tuchel, since sacked of course, was asked about the possibility of signing Messi as early as his Champions League final post-match media duties. The Ligue 1 champions have never shied away from splashing the cash – they paid Barca a world record €222million for Neymar and shelled out €180m on Kylian Mbappe. If Messi wants to win another European crown before retiring, few clubs are better positioned to help him achieve that, and the chance to link up with Neymar again might be too good an opportunity to turn down.
Even before there was any doubt about Messi's future at Barca, Inter were the main club linked with an audacious attempt to sign the 33-year-old. The Suning Holdings Group ownership makes them one of the few clubs alongside City and PSG that have the financial capacity to offer him a sizeable contract, and they do appear to be getting back to the level expected of them since the arrival of Antonio Conte as coach. Links with Inter have cooled in recent months, but they cannot be ruled out yet. The chance to battle old foe Cristiano Ronaldo in Serie A may prove an enticing prospect, too.
Things could have gone very differently for Barca had club legend Xavi been handed the reins in January instead of Quique Setien. As it happened, the iconic former midfielder felt it was not the right time to return to Camp Nou and chose to remain at Al-Sadd. A link-up with his former team-mate in Qatar could be an option for Messi, though there is every chance Xavi finds himself back in Catalonia in the not-too-distant future.
