Ever since FSG took over I've been trying to explain how they are not using a 'Moneyball' process in football. Moneyball has a strict and set definition, and you cannot use sabermetrics in a sport that relies on the gelling of 11 players instead of individual performance. FSG categorically do not use 'Moneyball' within LFC. Ian Ayre has stated as much.

Note this is not Moneyball which is what people seem to be confused about. The evidence is there that they don't want to sign the big names on massive wages so no one can refute that with anything more than opinion, as the evidence is weighty in favour of it. Which is not a way to win the title. But these are two separate issues.
