Where FSG have gone wrong is they held back with lesser buys over the years for 'prospects', now they have recruited a top manager in Klopp, in qualification for the CL, so they say they want to buy big, but this coincides with the TV revenue increase, so most selling clubs do not have to sell now, so prices have gone through the roof.
If they would have spent £100+million 3 years ago, we would have got 4-5 first team players, now your lucky if you get 2 for that money.
