Messi agreed to sign a new Barcelona contract a couple of months ago but it has recently emerged the Argentina international is yet to sign an extension.
And Spanish outlet Diario Gol claims that, despite the verbal agreement, there is a chance the 30-year-old will call time on his Nou Camp career.
Barcelona have endured a rocky summer, losing Neymar to Paris Saint-Germain and overspending on Ousmane Dembele, who arrived from Borussia Dortmund.
And Messi is known to be frustrated at how things have panned out.
The Argentina international’s entourage are said to have reached out to Barcelona highlighting the need to sign Angel Di Maria.
The pair are team-mates at international level and Lionel Messi feels his signing could be the ticket to Barcelona having a successful campaign.
It is said his camp even went as far to threaten the player leaving and Barcelona chiefs are now determined to grant him his wish.
Speaking earlier this week, manager Ernesto Valverde said all was well with his star performer.
“Messi seems fine to me,” Valverde said.
“He is training with us and seems to be the same as ever.
“I do not think there is any problem at all.”
Manchester City, meanwhile, have been tipped to sign him as a free agent should Messi’s frustration force him out of Barcelona.
