I wouldn't be so sure FSG would not sanction a £150 million player, if Klopp really wanted him (like with a VvD), if the club could get him, I think we would, but I think Klopp would balk at that sort of money.
Klopp's history is he likes to buy and develop players, to suit his style and improve them, so he doesn't usually buy many 'ready made' galactico type players.
I just hope Klopp doesn't become a Wenger when it comes to transfers, developing young players is very commendable but for a club like ours this cannot be the main thrust or we'll just end up as Arsenal after enjoying a great period at the beginning of Wenger's reign.
Klopp has however broken the record of buying the most expensive defender and GK, he will need to keep it up whenever we can afford and we can improve the team/squad, that's the only way to win things regularly and keep a significant fan base which allows for big sponsorships
