both dominated domestically and flopped hard in Europe. Don't forget Mancini went on to win the most competitive league with Man City.
Or maybe it's just because I don't rate Conte as much as you guys do; the Benfica scars still sting.
He won it when the league was collapsing to its current state, with by far the wealthyest team that he could pick with unlimited funds
Conte got a 7th placed team with a fucking lozer mentality that were hugely underperforming, and a few signings to help it. Compare that to what Napoli, Inter and especially Milan where fielding, and you get the idea.
Mancini failed in europe, without competition. Conte had 1 bad season in europe, but broke just about any record in serie a.
