Even if it's the ECC, it's still "only" Feyenoord, and it's something to be excited about for me. The reference was in that ligt, to the post I quoted - not to mean it's some great accomplishment or anything.
Emery isn't a realistic target currently imo, would Villa let him leave, would he even want to switch if he gets them into the CL? And (albeit under different circumstances), Emery has already failed miserably at a big English club as well, would that be something that really, really excites you?
I don't mind a risky hire if it's clear that the potential is there to create a "next big thing", so to speak. And imo the potential is definitely more there with a guy like Slot than some known quantity who has never achieved great things in his career. If Slot doesn't work out, it'll be clear soon enough and that's also not the worst thing in the world.
