Messi's family and some of his teammates were at the Camp Nou for the player's farewell.
Messi avoided speaking specifically about his future, saying he received offers from several clubs after the announcement that he would leave the Catalan club.
Barcelona announced Thursday it could not keep its greatest player because it wasn't able to fit a new contract within the Spanish league's financial fair-play regulations. The club's salary cap has been significantly slashed because of its huge debt. President Joan Laporta blamed the club's struggles on the coronavirus pandemic and particularly on the previous administration led by Josep Bartomeu.
Messi asked to leave at the end of the 2019-20 season but had his request denied by Bartomeu. The Argentina star had agreed to stay and had reached agreement with Barcelona on a new contract, but the club wasn't able to make it work because of its dire financial situation.
Messi spent nearly two decades with the Catalan club after arriving from Argentina as a teenager to play in its youth squads. He made his first-team debut as a 17-year-old in 2004, then played 17 seasons with the main squad. He helped the club win the Champions League four times, the Spanish league 10 times, the Copa del Rey seven times and the Spanish Super Cup eight times.
Messi leaves as Barcelona's all-time leading scorer with 672 goals. He played in 778 matches with the club, also a record. He is also the overall top scorer in the Spanish league with 474 goals from 520 matches.
He led the Spanish league in scoring in eight seasons, and was the top scorer in the Champions League six times. His 26 goals against Real Madrid are a record for the “clasico” matches against Barcelona's fiercest rival.
