It was bad at the Euro's even with him in the team. I think Hamrén needs to bring in a new assistant coach to sort out the defending, particularly from set-pieces.
The team is looking good going forward.
I'm a fan of the football we play, was at the euros too. Problem is that most if not all of the goals we allow are collective meltdowns and misunderstandings between defenders. That's on the coach imo. So I think you're right that he needs to add someone to his staff.
