Messi, 33, informed the Spanish giants of his desire to end his 19-year association and will activate a clause to unilaterally end his contract in the current transfer window.
The Barcelona captain is said to have informed the club he wanted an 'immediate' exit in the aftermath of the 8-2 mauling at the hands of Bayern Munich in the UEFA Champions League quarter-final.
While club president Josep Bartomeu denied he will be allowed to depart with a €700-million release clause in his current contract, Messi reiterated his desire to leave to new head coach Ronald Koeman in a private conversation.
Now, according to TyC Sports, the record six-time Ballon d'Or winner has confirmed that his glittering era at the Blaugrana has come to an end.
