Liverpool lost 90M from 2011-13. 50M in the 2012-13 financial year. I don't think they failed FFP because they were able to write down expenditure on infrastructure and inherited debt. They had a lot of exemptions. They had a net spend of 17M last season, so I don't know what their losses were (if any). But they did have a bumper new contract with Suarez to take into consideration and of course the new signings.
I doubt their owners are in it to run losses for very long. They'll be happy to have CL money this season but I am sure they will be wary of how sustainable or unsustainable it is to rely on that income. The 75M they get for Suarez is going to be eaten up by Can (10m), Origi (10m), Lallana (25M), Markovic (25M), Lambert (4M) and Lovren (20M). All decent signings I think, aimed at greater squad depth, but none that will make them a better team immediately. If they get 75M for Saurez, that'd be a net spend of around 20M. I doubt, given the losses they've made, the increased wage bill from adding 5 (net) players to their squad, that they are going to spend much more than 20-30M net. I'd be amazed if Markovic isn't being sought as an alternative to Sanchez, who seems set to move elsewhere.
Plus, they have to think about replacing Gerrard within 1 or 2 seasons, and probably signing a fullback or two. My impression of Liverpool, since Fenway took over, is that they have turned the corner from the shambolic transfer approach that has marred them for the last 20 odd years. I've been impressed with how players like Coutinho, Sturridge and Henderson have turned out to be excellent purchases, at decent prices.
