Yep. Spains problems are pretty well known. Comfortably outspent by Ligue1, Bundi, Serie A and (obviously) EPL these days.
Worse than this is two things,
1) no growth expenditure due to FFP
2) no income due to 1:1 (some clubs like ours on 1:4) and buyout clauses.
Answer is self imposed austherity while all assets (Players) go elsewhere. The clubs spend little, and the clubs make little. Carry on like this and it will soon be behind Portugal too, as no club in Spain can sell on players like their big 3.
