Completely different scenario. Bielsa was out of work. Would he have walked out on Bilbao to come to us in February?
Absolutely not.
We as fans can see the potential of this club, in fact I'd go as far to say we vastly overestimate the potential of this club in the current world of football. Outsiders don't see us as a huge global club. Even if I was Thomas Franks personal advisor I'd tell him to stay at Brentford. Same with Kompany, they are on the crest of a wave, we are...erm...on an 18 month hellish run of results.
You could even go as far as Slot at Feyenoord and Iraola at Vallecano. They should stay where they are as they are on the cusp of doing something great where they are. We are not the catch of the century that alot of us think we are.
