Just noted that the Serie A channel on Youtube grown heavily since this season ... The Ronaldo effect? They also have now proper English commentators on the highlights instead of Italian or Indians who try to talk English
For example:
Udinese - Juventus 4.000.000 views in one day.
Best viewed this season: Juventus - Sassuolo 8.400.000 views
Best viewed last season: Juventus - Napoli 1.200.000 views
Best viewed this season (not Juve): Napoli - Milan 2.000.000 views
Best viewed last season (not Juve): Benevento - Milan 1.200.000 views (goalkeeper scored in 94th minute)
