Andersson believes that injuries and lack of playing time for several players are behind the tough year.
- This year has been a very busy year to be the national team captain, I admit that.
With all the injury problems there have been, looking back, it has been something incomparable, I must say, he says.
- Plus we have many players who had difficulty getting playing time in their club teams.
"I feel a frustration"
Andersson doesn't know why the players don't get enough playing time.
- Somewhere you start to think about why it is like this.
Maybe it's just a coincidence.
Suddenly we might be sitting here in a few months and then it will be completely different, he says.
- I feel a frustration in this because I cannot influence it.
I have to admit that.
Feels great confidence
Sweden meets Slovenia tomorrow, in a match that will decide whether they will remain in Group B in the Nations League.
Add to what's at stake, it's a confidence for you too, is it one of the most important matches of your career tomorrow?
- I feel enormous trust in my surroundings.
I don't have a thought about that, he says.
- However, it is a hugely important match, we don't want to fall out of this group.
It is an important match from that perspective.
Then I've been involved and lost many times.
I had a summer with Norrköping where we didn't win in eleven games.
I have been with before when it received.
The way forward is to learn what you have done and move on, and then you move on to the next task.
