To be honest, beating a mid-table EPL team in a city called Baku one night is miles behind anything he did at Napoli, in my opinion. But to some, this is like checking a box in order to coach Juve. Realistically, if you win the EL, you're still like the 30th best team in Europe ffs.
The criteria for evaluating coaches is so black and white, it's like a see-saw.
