For the correct (all, add-ons, youth, loan etc), for the last 5 years of City and all current PL teams, look no further than the @BlueBrain twitter (you don't need to be on twitter to look):The problem with these kind of lists and studies are nobody bothers to fact check them. Its the classic flood them with data so they dont even question it act.
They'll be dozens of incorrect prices, a huge portion will be complete guesses and they often flat out miss youth sales and post-sale clauses
Marvellous research and time spent
