The 1:1 rule in La Liga allows teams, such as Barca, to spend all money raised from player sales or wage savings on new players. Up to this point, however, Hansi Flick's side have been operating under the 1:4 rule, which means they could only spend one euro for every four they saved or brought in. While they still have huge debts, their ability to address those will be greatly improved with the aforementioned financial deal.
