Prior to the COVID-19 pandemic, Barca had the largest cap in Spain's top flight in 2019-20 at €671 million.
However, La Liga's new limit for the 2020-21 season was €382.7m. The Catalan club were given some leeway in terms of reducing salaries, but it meant they were unable to register
Memphis Depay despite agreeing on a fee with
Lyon last September.
La Liga could technically prevent them from registering Messi's new contract or inscribing new signings this summer if they don't adhere to certain financial regulations.
