I belive there is a gentleman's agreement between Pirlo and AA to at least let him finish the season,since before he took the job.
Pirlo’s career as a manager has already gone down the drain . He should be at least given the courtesy to finish the season, if he doesn't resign that is .
Another matter is : Why does Pirlo who knows that he has failed , although not yet mathematic, doesn't resign.
Is he still hopeful that we are going to miraculously turn it around?
