Messi has an early break clause in his Barcelona contract.
As Barca look to re-sign the 33-year-old superstar, he is reportedly ready to walk away next year.
The Argentina captain will leave Camp Nou when his contract expires at the end of 2020-21, according to Cadena SER.
Barca captain Messi – previously linked to Inter and Manchester City – has reportedly been in talks over a new two-year deal at Camp Nou.
However, the six-time Ballon d'Or winner and Barca's all-time leading scorer is reportedly tired of being blamed for issues at the club, with the LaLiga champions set to be dethroned by Real Madrid.
