The big difference is Palace, like most clubs, have a director of football. They selected Viera and have given him the tools for the job. If he fails, they will replace him quickly. Just as if he's half decent and bins them, they will replace him quickly.I don’t think Cannavaro would ever be my choice, but I could maybe get on board with it as a summer appointment. Like Palace taking a risk on Viera. If he’d failed miserably they could have got rid after 10-15 games and still been fine.
That happening now for us would mean certain relegation.
Everton are a different animal and different to almost every team in the league.
