Lionel Messi has struck a deal with Paris St-Germain to join the French club following his shock exit from Barcelona, BBC Sport columnist Guillem Balague said.
The case is submitted for a medical examination.
The 34-year-old Argentina captain left Barca – the only club he has ever played for – as they were unable to afford a new deal under La Liga financial fair play rules.
Mauricio Pochettino’s PSG finished second behind Lille in Ligue 1 last season.
Considered one of the greatest players of all time, Messi has scored a record 672 goals in 778 games for Barca, the club he joined at the age of 13.
He won the Ballon d’Or a record six times and won 35 trophies with the Catalan club.
The signing of Messi – who would reunite with former Barca teammate Neymar at Parc des Princes – is one of the most notable captures in football history.
Barring late hitches, he will become PSG’s fourth free transfer this summer after the arrivals of midfielder Georginio Wijnaldum, defender Sergio Ramos and goalkeeper Gianluigi Donnarumma.
Highly rated right-back Achraf Hakimi has also joined Inter Milan.
