He doesn't look like a natural goalkeeper. Every save looks awkward and wrong.
Technique, handling and footwork.
Good lord the Dutch system is so crap, it's so overhyped and arrogant. Any manager that comes here gets found out so quicky.
All this crap about angles and positions is all footballing homeopathy, sounds good, on paper is good but in reality it's crao. They can't set teams up, they struggle if another team actually tries against them, they can't motivate players, and they focus so much on their own hot air about how football should be played that they end up creating nothing.
A keeper like Onana should be playing for Utrecht. He's wonderfully under par.
