Barce and Real Madrid especially have HUGE problems complying.
Madrid payed for their last spending spree on Ronaldo through loans from banks with small interest (Something to do with the King Of Spain and his power with the Spanish banking system), Barce are in 746ish million euros debt and that's why the stories coming out that they have banned colour photocopying at the stadium to save money yet are rumoured to be bidding 35 million for Fabregas...
Best placed teams going into Financial Fair Play:
Bundesliga teams + Arsenal, possibly United depending on their balance sheet.
Udinese are well placed as well surprisingly, think when they last restructured 10 years ago they set out a plan and stuck to it so they could be a coming force of sorts in Italy. Inter+AC still have huge debts structured in bonds that Moratti/Berusconi stopped clearing outright years ago I believe, Serie A is in a huge mess at the minute simply because half the clubs don't have all seater stadiums that are adequate enough...
Juve recently built a new Delle Alpi in the biggest stadium budget in Italy for years...41k is the capacity of that BUT they believe they are a step ahead of every other team in Italy by restructuring over the last couple of years...Teams are trying to change but FFP will just help them along the road a little bit.
