When
Moyes left it was time to go. But he did a lot of good here. Brought in 2 of our all time best players (Cahill and Arteta) for peanuts (plus brought in peanuts). The squad was always likable and for what they lacked in talent worked their tails off. Was a bit unlucky (Fiorentina, Jelavic was 75% the player he was the his 1st 1/2 season we'd have had 4th and maybe even 3rd that year). Wasn't as overly defensive as some made him out to be, we were a possession side his last 2-3 years.
Other than Real Sociedad don't think he's been a bad manager post career. At Utd he wasn't allowed to spend money, RVP (who dragged them to a title the previous year) got injured again and there were a bunch of vets well past their prime. VanGaul spent a bleep-ton of money and did about the same. Sunderland utterly collapsed after he left (they would have completely collapsed if he stayed, and probably would have collapsed if freaking Brian Clough was their manager). WH is a mess right now after spending like Koenman this summer (though WH won't get relegated because good lord the bottom of the table).
I'd take him for the USMNT. He'd probably bring the team together and play hard (2 things they are extremely lacking and are correctable). He can build squads around journeymen strikers and goal scorers that aren't exactly mids and arent exactly strikers like Pulisic. Though the sediment here is to bring a "tactical genius" to "transform us into a world class side". Which is pretty laughable that people think we can bring in a bunch of limited talent players for a week or so every 2 months and turn them into Chile or the 70s Dutch sides. We tried this w/ Jurgen for years yet people never realized that sure you could play just like Germany when you have some of the best players in the world.
As far as him coaching another prem club though, yea they'll play hard and together. However his best trait, finding gems in the low end transfer market isn't really possible. We got Baines, Jags and Lescott for about 13M, that trio would cost 100+M in today's market. And guys like Arteta and Pinnear, who rode the pine before we bought them don't get unloaded for a pittance anymore. Championship stars like Cahill go for 20-30M now.
