Hien is a big question mark ahead of the match that decides everything - the final for a World Cup spot against Poland at home in Solna on Tuesday.
With Gudmundsson there is no danger.
"It's the same as always. Take care of your body and make sure you're ready for Tuesday," he says.
Did you want to try to play through the pain and keep playing?
"Of course, I wanted to, but it was a trade-off and it felt good."
The feeling after 3–1 against Ukraine?
"It means an incredible amount, not just to us but to everyone else as well. There are a lot of positives to take away from this match. We will take that feeling with us."
