Laporta said at a press conference to introduce newcomer Jules Conde from Seville that Sosios will be Barcelona’s technical partner under this agreement.
Barcelona uses many mechanisms to increase its revenues in order to compensate for losses, reduce debts and meet the rules of financial fair play in the Spanish League.
The deal comes after the club last month sold another 15% of its television rights to American group Six Street, giving the group a 25% stake.
Barcelona signed Brazil winger Rafinha from Leeds United and Polish striker Robert Lewandowski from Bayern Munich after Six Street bought the first 10% stake.
Laporta, who headed the club in one of his best periods between 2003 and 2010, said in August 2021 that the club’s total debts of 1.35 billion euros, of which 673 million was owed to banks.
In June, Barcelona agreed to sell a minority stake in its licensing and marketing division and give up up to 25% of its income from television rights to La Liga matches.
The club also signed a shirt and home sponsorship deal with Spotify in a €280 million deal and agreed financial plans in December to renovate the Camp Nou.
