Rangers wasn’t the right fit for him in the end but he wouldn’t have got us within a kick of the Europa League if he was a complete dud.
To an outsider the obvious achievements he can point to are the EL run, winning the SC and taking us to the CL for the first time in over a decade. We may be second at the moment, but given Celtic have won 10 of the last 11 league titles I don’t think many foreign chairmen will hold that against him.
He is very well respected within the game and will certainly have offers.
Could see a lower half Bundesliga or La Liga team being an option for him.
