My prediction before the season started was one big name and one "who?".

I may have to downgrade my expectations.
Honestly, don't care if we don't sign anyone this summer, let Slot get a good handle on who he has under him and then back him properly in future windows. I'm not expecting a title push first attempt out, rather play the long game.
One thing I admired about Klopp was his transfers were never a numbers game. It was about getting the right players and only the right players.
Compare that to the last successful manager we had, Rafa... with Rafa it was always wheeling and dealing with numbers coming and going continuously. (Of course, understand it partially had to be that way because H&G wouldn't back him and he had to sell to buy).
I'd rather an FSG/Klopp approach to transfer windows than the H&G/Rafa approach.
