Lionel Messi will sign a new Barcelona contract when he returns from his honeymoon in the middle of this month, Goal understands.
The Argentine attacker, who married long-time partner Antonela Roccuzzo in Rosario on Friday, was set to return to the Catalan capital with his family at the weekend, but will now not be back until around July 12.
After the wedding, Messi and Antonela changed their plans and are now on their honeymoon with sons Thiago and Mateo on the Carribean islands of Antigua and Barbuda.
On July 12, Barcelona's players are expected at the training ground in Sant Joan Despi for medical examinations ahead of the club's pre-season preparations, so Messi will be back for that.
The five-time Ballon d'Or winner is out of contract in 2018, but a new agreement is all but finalised after months of negotiations between the player, his father Jorge and the club.
Messi will put pen to paper on a fresh agreement that will take him up until 2021 with the option of one further season and the deal should make him the world's highest-paid player with wages in excess of €22m per year after tax.
After playing at the World Cup, the Copa America and the Copa America Centenario in the last three summers, Messi has had a rare break this time and will therefore return to training along with the rest of his team-mates to prepare for a new season which kicks off with a Spanish Supercopa series against Real Madrid in August.
Messi's and Antonela's wedding was a big Barca affair as team-mates past and present were invited to the party in Rosario, with Carles Puyol, Xavi, Dani Alves, Samuel Eto'o, Gerard Pique, Neymar and Luis Suarez all in attendance.
The Argentine made his Barca debut in 2004 and has won 30 trophies during his time at the Catalan club, scoring more than 500 goals. This new contract could see him retire at Camp Nou.
