Lionel Messi could leave FC Barcelona without a transfer fee if Catalonia ceded from Spain and the club did not compete in any of Europe’s top four leagues.
El Mundo, a leading Spanish newspaper, on Friday reported this, citing a clause in his new contract.
Barca’s all-time top goalscorer signed the contract in November, seven months before his old deal expired.
It runs until June 2021 and contains a 700 million euro (£623 million) buy-out clause.
But according to the Spanish daily, it would also allow the five times World Player of the Year to leave the club where he has spent his entire career for free.
This will be if Catalonia’s independence push resulted in Barca exiting Spain’s top flight, and not joining any of English Premier League, Bundesliga or Serie A.
A Barca spokesman declined to comment directly on the report, but added: “In the interests of confidentiality, the club never comment on contracts signed with players and never will.”
Messi’s management team could not immediately be reached for comment.
The political crisis triggered by Catalonia’s independence drive remains unresolved after separatists won a slim parliamentary majority in a regional election last month.
Argentinian Messi’s latest contract was signed on November 25, before that vote.
But after an autumn referendum on independence, which authorities in Madrid declared illegal, it dissolved the region’s political institutions after they ratified it.
The referendum had direct ramifications for FC Barcelona, who, on the day that it was held, chose to play their La Liga game against Las Palmas behind closed doors.
The decision was however in response to police violence against would-be voters.
The President of La Liga, Javier Tebas, has repeatedly said FC Barcelona would be booted out of the Spanish league along with all other Catalan clubs in the event of independence.
This is because only teams from Spain and Andorra are legally entitled to compete in the Spanish leagues.
Barca, who have won 24 Liga titles and lead this season’s standings by nine points, said after the referendum they would not speculate on the future.
However, they were “not planning for any other scenario than playing in the Spanish league. The club is competing in this competition and wants to win it.”
