You had to resort to calling someone a cretin to make your point. What an amateur. Better try reddit if you can't get any better than this.
Thiago and Kroos deals were not fancied by the respective managers.
Missing out on Klopp has nothing to do with the finance team, it was because the CEO couldn't sell the club properly to a proper manager.
Signing Sanchez was lauded by everyone at that time but moaners like you will use hindsight to death and try to make a useless point. It has nothing to with the finance dept again. The board was comfortable giving those wages to a 'then' great player Sanchez and you can't really blame them for Sanchez's poor form. But yeah keep moaning.
Fellaini can't be justified but it's more on the transfer planning committee I would say, which couldn't get Moyes the first choice targets he wanted.
Of course I have my fair share of problems with the negotiators and CEO and I bash them all the time. But I won't sit here behind a keyboard pretending to know better than people whose job is to manage millions on a daily basis.
