If we weren't in such a pressure situation I would have said Arteta from City. Good reputation, learned from arguably the best manager around, would go over well with the fans, and not too big for us at the current stage of his career. I would also consider Bielsa from Leeds, seems a bit mental, but could instill a winning mentality and he seems like he has some tactical nouse. We can't kid ourselves that this would be a job that would be appealing to people like Mourinho so lets not even go there.
I think our appointments have been bad since Moyes left:
1. Martinez got Wigan relegated.
2. Koeman was sacked before he went to Southampton and only really did well there off the back of what Pochetino did the year before.
3. Silva never stayed at a club past one year since his first appointment, and was sacked by Watford before he came to us.
If Silva goes, however, I'm expecting us to announce the return of Allardyce or maybe Ranieri cos that is the kind of stupid thing that we would do. Only joking about those two, but I can genuinely see Moyes being offered a contract till the end of the season - even though I personally think that would be a backward step.
