Sergio Busquets and Jordi Alba also help the Club to register team mates thanks to their salary cuts

The salary reductions for Sergio Busquets and Jordi Alba, two of the four first team captains, signed this Tuesday have allowed FC Barcelona to achieve two objectives: the registration of Sergio Agüero with the Spanish Football League (LFP) and to extend the Club's limit with regards to financial fair play regulations. 

Sergio and Jordi Alba have agreed to changes in the financial terms of their contracts which included a wage reduction for this season and the deferment of payments for the remaining years. 

The gesture from the two players comes after the agreement recently signed by Gerard Piqué which also allowed his team mates Memphis, Eric Garcia and Rey Manaj too be registered with the league. 

As such, FC Barcelona has completed the registration of its players with the LFP.
