So, after the clown show of the last six days, we now, formally, start the search for a new boss.
I'd imagine Robson will be caretaker, but I'll say the same thing as I've said when Glass and McInnes left.
The new manager won't matter a damn without a wholesale overhaul a the club.

Gunn has to go.
I feel a bit sorry for him, he was effectively a pen pusher but got hoisted into one of the most important roles in the club.

A lot of ignorant, dinosaur, types dinna like the job title "Director of Football" it can mean so many things, but to appease them we need a General Manager/Chief Exec....whatever, in to oversee EVERYTHING.

Recruitment has been a disaster for the reign of the last two managers and the majority of the one prior.
Scouting and recruitment needs torched and re-built.
Youth development, well, McKenna and Ramsay papered over cracks, but that's another area that needs work.

The days when the manager oversees these two most fundamental areas of the club are long gone.
I'd be tempted to leave Robson, with a short term staff, in charge until the summer by which time we MUST have a DoF in place.
Having said all that, I'd imagine Swiss Toni will probably go for Jack Ross.
