Structurally I'm nigh-on certain that they're going to do the right things, but my impression is that they also expect us to immediately become serious promotion contenders. Otherwise why fire Dyche?... and patience. Change for the better takes time, I'm sure the Pozzos understand that and hopefully the fans can look 4 or 5 years ahead, not 1.
By firing him they have raised the short term expectations. In most fans' eyes, even those who realise that we could do all the right things yet still take years to win promotion, Zola will be considered to have failed this season if he doesn't match or better Dyche's record in 2011/12.
