Lionel Messi tells Barcelona he wants to leave

Lionel Messi informed Barcelona his desire to leave the club after nearly two decades. The club confirmed to multiple outlets they received a document via burofax, a service used in Spain to urgently dispatch a document that requires proof to third parties.
Messi used a a clause in the contract that should oblige Barcelona to let him leave for free, but the divorce between Barcelona and their biggest idol could turn into a legal battle as the club stated it won’t automatically grant the Argentinean great his wishes as the club believes that the particular clause expired at the start of the summer.
