Messi sparked the biggest transfer saga of the summer by handing in a transfer request at the Nou Camp last week, informing Barca chiefs of his desire to leave via burofax.
The Argentinian superstar is understood to be seeking a new challenge after 16 years in Catalonia, with Manchester City leading the race for his signature.
Yet according to Italian journalist Tancredi Palmeri, Messi has agreed to stay for one last year at Barca despite his intention to leave.
The player’s father and agent Jorge has been holding talks with club president Josep Maria Bartomeu, who remains adamant that Messi still has a year remaining on his current contract.
And with a £623million release clause inserted in that contract, it is highly unlikely a potential suitor would be able to afford him.
Messi has therefore agreed to stay put in Barcelona for another year, according to Palmeri.
He posted on Twitter: BOOM! Jorge Messi saying to [Spanish outlet] Deportes Cuatro “yes” to question of staying one last year at Barcelona”.
It is believed Jorge had argued that his son should be allowed to leave due to a clause in his contract which allows him to depart for free at the end of the 2019/20 campaign.
However, Barca have insisted there is no such clause and remain determined to keep hold of their star man.
News of Messi’s decision to stay at the Nou Camp will come as a major blow to City, who had reportedly agreed to pay the Ballon d’Or great £623million over five years with Pep Guardiola’s side and affiliated club New York City FC.

According to the Daily Record’s Duncan Castles, the City Football Group reached an agreement with Messi over a deal that would see him spend three years in Manchester and another two in New York.
The report quotes a source close to the player as saying: “Messi thinks Guardiola took the best football out of him, and he wants to repeat that.”
