A four-year deal has been on the table for the diminutive Argentinian since the summer, but while terms have been agreed, he has not yet signed the contract.
And with his contract expiring in the summer, there are growing concerns that the 30-year-old could walk away from the Nou Camp for nothing.
Javier Tebas says that unless he has been lied to, Messi has signed a new contract with the club
Barcelona president Josep Maria Bartomeu previously said Messi’s father, his representative, had already signed the contract and it was just waiting for the player’s signature.
But Tebas is convinced one of La Liga’s most important players has already signed a new deal.
Speaking on Tuesday, Tebas said: ‘Messi has a contract which has been renewed.
‘Contracts are official when they are signed and not when it is announced that they have been signed.
There has been no announcement over whether Messi has signed a new deal at Barcelona
‘Messi has signed with Barcelona, if I have not been lied to, he has signed.’
Team-mate Andres Iniesta recently signed a ‘lifetime’ deal with the club and Barca CEO Oscar Grau recently suggested he’d like to see Messi do the same.
‘The idea is for Leo, who has been here since he was little, to stay here for life because he is an icon,’ said Grau.
‘After his playing days we want him to continue to be linked to the club.’
The 30-year-old would be able to leave the club for nothing in the summer without a new deal
