Some fans at Camp Nou booed Jordi Alba on Sunday amid reports he refused to lower his salary
Barcelona defender Gerard Pique has insisted that all four of the club's captains will eventually take a pay cut.
The club has already confirmed that Pique's salary has been "substantially reduced," which allowed Memphis Depay, Eric Garcia and Rey Manaj to be registered for La Liga's new season.
Pique has insisted that fellow captains Sergio Busquets, Sergi Roberto and Jordi Alba will soon follow his lead amid Barca's dire financial situation.
