juve hired Pirlo due to financial issues, they can't afford Pep surely? Allegri yeah but would he return? He might fancy coaching abroad instead.
If they are too much patient with Pirlo there is a chance that they lose even the CL spot for the next season!Well they may get Allegri midseason, but Pep/Zidane are only possible at the end of the season. I guess juve will be patient with Pirlo though, because firing him after a few months would make them look bad.
