Timing is important too. Not to diminish Allegri, but in my lifetime watching Conte win his first after Inter had won consecutive titles after Calciopoli was a massive achievement. Lippi's competition was tough, there were so many teams back then with exceptional players that could win games alone. Difficult to compare, Italian teams were very good in Europe too.
Napoli did great last year, but they had little pressure from anyone. This year Inter have kept an extremely high pace, but for once the pressure is on them more than us being expected to win.
