Leo Messi could walk away from Barcelona in 2020.

Mundo Deportivo says Barça are planning to extend Messi's contract by one year, taking him to June 2022.

But it's suggested the Argentinean ace has a release clause written into his contract which would allow him to leave Barça in 2020 “on the condition that he doesn't join an 'elite club'".

Officially, Messi last renewed with Barça on 25 November 2017, extending his contract until June 2021.

Messi also has a release clause which would allow him to leave in June 2020. While president Josep Maria Bartomeu is keen to keep to his word, he wants to ensure that Messi agrees new terms with the club.
