I think the final will be entertaining. Ajax creates chances and won't be afraid. They are young and inexperienced which often is a disadvantage but against a park the bus team like Mourinho's side it can play in their advantage.
Ajax creates chances, shambles at the back.
United solid at the back, shambles in creating chances.
I really fancy Ajax to win it, perhaps naive from me, but I think it's not too far fetched over a singular game.
