Define celebrate, I mean Juventus are way higher than Serie B, if you mean like a Scudetto party, no nothing extravigant, but if you mean by a celebration just congrates on a job well done after a difficult season faing many troubles that the hit the squad in the summer and at the end the team managed to go through an ordeal and become again in where they truely belong, then yes celebrate.
Juve have a right to et back and showed how they outclassed Serie B clubs this season, I was though expecting a lot more signnings than till now and bigger players as well, but so far the team is becoming better and better
