Barcelona will appeal a court ruling which ordered midfielder Gavi's first-team registration to be reversed, a source told ESPN on Tuesday.
The dispute stems from LaLiga's refusal to register Gavi's new Barca contract because the Catalan club are deemed to be in excess of their spending limit beyond the end of the season.
Barca sought to overturn LaLiga's decision and, at the end of January, a judge obliged LaLiga to temporarily proceed with the Spain international's inscription as a first-team player.
However, a court ruling on Tuesday, as first reported by ESPN earlier this month, said Barca missed the subsequent deadline to officially file their lawsuit.
