Sorry, some of us don't have as much time to go into it as deeply as you.
On the surface, it appears to be a similar appointment to that of the standard of Martinez.
Perhaps that's the standard we're truly at I guess.
I would agree, but only in that he's an unknown at our level and resources. Martinez was a gamble, which we lost. While there is a risk of that being the case for Silva, it's also possible it could go the other way.
Unfortunately, without the clout to pick and choose from the world's proven best, the only way we can hope to get a top manager is by taking a punt. In that respect, Silva seems as good a bet as most.
Plus I've never heard him say phenomenal.
