Ask Leeds United.
Of course we should celebrate. We won't celebrate it in a "F$@# yeah, we're the champions!" way, but our players dug in and played hard, despite the points penalty, and the fact that many of them had the choice to leave for greener pastures.
Winning Serie B itself is nothing to go nuts over, but we're back where we belong, and I think that's cause for celebration.
I think there's a bit too much of a gloryhunting mentality with Juve supporters. Would you not celebrate winning the UEFA Cup because it's not as big as the Champions League? Realistically speaking, the UEFA Cup could be the trophy we're gunning for in 2 years' time, and I won't be embarassed that my team is playing at such a 'low level'.
It seems we're pretty polarised on the issue. 12 votes apiece.
