valencia's case is a small look at the state of la liga to be honest, outsude of the top 2
All of the teams outside of the top 2 make little profit (TV rights) and can spend hardly anything. The ones that did spend a lot in the 90's and 00's collapsed quickly (Real Sociedad) or are in dire straights today. Name me one club other than Barca or R. Madrid in La Liga that can spend big on players. The Prem has plenty more than two. Even Barca will have to stop, they are in a lot of debt and even had to start putting sponsors on their shirts this season. I bet we don't see much spending from them in the next few years. I think Real may have hit their ceiling too. There are plenty of teams in the Prem though with wealthy owners who can shell out as much as they need to.
