My post got deleted and I thought it was worth re-stating Gabbanini's answer to this very point.
“As a chief scout, I can achieve the best level in the world, but I probably wasn’t the top sporting director for Tottenham. So when you want to be sporting director like I do, maybe you need to take another path, start with another club and maybe, one day I can come back (to a club like Tottenham) as sporting director,” he says. “The club needed someone like me at that moment (when Paratici left), but I don’t think that the club need someone like me now.”
I really liked this interview as it gave real insight into thinking and roles and shows a level of self-awareness on his behalf.
