if we are really looking for a caretaker then we should unleash the vecchi.
simple reasons: new name, thus unpredictable, cheap, gets his chance to prove himself and be a longterm option, prefers attractive football from what we see in the primavera, has already been pro coach (yes only serie b, but not as green as strama was), has already maintained the pro license with a perfect score, which proves atleast theoritcal knowledge (another plus in comparison to strama), can perfectly weigh up if bonazzoli is able to take the fourth striker role or not, because he knows him the best.
and last but not least, yes there is potential that he might fail, but there is also potential that he succeeds, which i honestly dont see in mazzarri anymore...
