This is really funny, for a coach who messed up everything for the fans in the champions league final could not wait for this disgrace to settle at least 2 weeks before running from the club, wow what a move. If it were some coaches I don't think this move would have been possible because they will make sure to cover up for their mistakes and not to fly away just like that, I wasn't expecting this move from Inzaghi. This club still have hope only if they do the right thing because I don't expect some of the players to still be at the club if not they'll struggle to stay in the top 4 just as Napoli did last 2 seasons I think.
It's not the first time that happens this type of situation: back in 2010, after winning the Champions League, Mourinho immediately jumped in a car and left the stadium without even celebrating because he was signing a deal with Real Madrid. And he did something similar even back in 2004 (I think) when he won the Champions League with Porto but he was already thinking about Chelsea.
