The vice president of FC Barcelona said Thursday that star forward Lionel Messi has not yet signed the contract extension that runs until 2021.

Jordi Mestre's remarks came hours after Barcelona lost the Spanish Super Cup to Real Madrid 5-1 on aggregate.

Mestre, speaking during the introduction of Brazilian midfielder Paulinho, said the two sides reached an agreement and were just waiting for a date to sign the contract.

The club official said he was confident that Messi would sign the contract extension.
