At 47 years of age I have seen many great players and coaches leave Juve, and Juve is still there, at the top.
I am grateful to Conte for bringing back pride to the Club but I have to admit I have been puzzled at some of his choices (eg: the team that played Benfica away, to mention one ...). I don't know what exactly happened, but if the Club made that decision, they probably had not other choice.
