No Carlo's was not. Maybe you can argue Milan was, but the Chelsea side he took over was a year removed from a CL final, Bayern is Bayern and Real Madrid was a recent title winner with a top 5 player all time at his apex in the team. Conte's rebuilding of Inter and Juve far exceeds any of that.
Nuno got Europe once with Wolves and his style of play will not be doing better than 6th or so. It's stability but is stable mediocrity good enough? For me the pick needs to have more upside if we're taking that approach.
I think there are guys I'd take over Conte but it just isn't Nuno.
Nuno is not comparable to Conte, iv e said that, but to be fair Nuno got Wolves into Europ twice in the last three years. I just want a manager to stay more than 18 months, I don't think Conte will do that, I highly doubt he'll come anyway.
