It's a strange appointment isn't it. Of all the names listed he's pretty near the bottom, and you are right, I'd have Moyes over him as well.
We rejected him for Martinez 6 years ago (wrongly in my opinion) but his career appears to have really bombed since then.
What concerns me is that it smacks of Moshiri and favours to agents. It worries me as I am not sure it's the best way to run a football club, thats not to say it's not worth keeping agents sweet but you also have to have a central approach.
I'll always get behind a manager, but I am not sure he's anywhere near the optimum candidate. I'd even go as far as saying his CV is less impressive than when Silva arrived.
