I agree, I hope it works. But he has put himself in an extremely weak position, witness the "team spirit" prompt by the brother.
He'd run out of clubs to work for in the Middle East.
He's not Darren Kelly in the fact he is very experienced, despite his top level experience being eons ago. Well 2 spells, half an eon and an eon ago.
All his past clubs seem to have had money, something lacking here, so he is going to have to draw on skills from a very long time ago. It doesn't fil me with confidence.
