Take it one stage further. If there were a theoretical 'Manager draft' of the 20 PL Managers (as of this morning) and fans had to pick which manager they would like to manage their team, what would it look like?
Pep and Klopp would be in or near the top 2 for most fans of any club.
Then the likes of Tuchel and Rodgers. Then maybe Moyes, Potter, Benitez, Bielsa, Frank, possibly even Vieira.
Lage would be high on my list, but he's an unknown to most. I think given his extensive coaching background and his knowledge of tactics, he could probably get more out of your current squad than Ole!
Where would Ole be? I'd hazard a guess that he'd be down near the bottom with Farke and Jones.
Extend that into the Championship and I'd doubt there'd be many top half clubs that would swap for Ole.
Who will employ him when he is inevitably sacked?
That level just shouldn't be accepted for a club of your size.
