Inter were a big club even before Calciopoli, particularly because of their past honors. They just spent a ridiculous amount of time not winning anything.
Yep, fan-base, trophy room all points out to their big clubness. No, not like Nottingham Forrest. They're above Valencia/Roma level come on.

= European grands both traditionally and currently,
notice how the likes of Chelsea, Man City, At Madrid, Borussia, Roma, Sporting, Valencia, Marseille don't qualify.
Also IMO the French league never had a
super club.
