I think Zaccheroni will do well. IMHO he is the best "available" option. He is definitely better than Gentille. (I saw few matches of the Azzurini while he was the coach. His style was boring and defensive.) Gentille has no experience at club level. So he is a very risky option. Other options...
According to La Repubblica, Zacceronei will be announced tomorrow morning if Juve suffer a heavy loss tonight. Otherwise, the decision will be delayed until Sunday. If Juve win both matches then Ferrara may remain!!!
Nothing. Ferrara will remain until Thursday (and possibly until Sunday)! The board decided on an interim coach rather than a long term solution. However, they did not agree on who is the interim coach.
Ferrara lacks courage and experience. I saw individuals not a team. I thought things will improve but seems this is not the case and Ferrara needs to be sacked.
