Not forgetting Liverpool failing FFP in 2013 and only escaping punishment by UEFA because they failed to qualify for Europe that season.
Then they were on the brink of failing FFP in 2015 but suddenly conjured up £35 million in 'stadium development expenses' specifically for the non-existent Stanley Park project which was initiated by Hicks and Gillette and no construction had been started by January 2012 when FSG canned the project. No details of how they could spend £35 million on a project that literally never got off the ground was made public but UEFA passed it and allowed the £35 million to be offset against Liverpool's FFP losses. (Take a bow R. Parry). This stunk to high heaven and my own feeling is that they held these 'expenses' back for a rainy day and produced them like a rabbit out of a hat when they were in deep shit in 2015 despite Hicks and Gillette having sold the club and ridden off into the sunset in 2010.
No Liverpool fan I've ever mentioned these two FFP breaches to either knows or admits to knowing anything about them. Some insist that these stadium development expenses were for Anfield but they weren't. The expense claim for Anfield also lodged with UEFA at the same time amounted to only £14.9 million, well under half the amount claimed for Stanley Park.
Maybe the PL can explain why they've not investigated either case but of course they won't.
