A bit late to this but thought I'd give my opinion anyway.
Overall, his sacking isn't surprising. His season there was shorter than his time with us but had similarities. After a brilliant start, he started to come undone.
I believe his football isn't sustainable beyond 10 games. This is because it uses too much energy and running which isn't realistic over a full season. Having said this, I actually think it would be perfect as an international manager.
