Kim Nilsson is one of those who was already in 2010 and played the World Cup final then.

- What I remember most is when we first sing the national anthem, you only hear the closest and then it was Finland's turn and you just "what happened now?", He says.

Real challenge

Finding the communication and the game without being able to hear each other was a real challenge and therefore real speakers are in place at the training.

The sound has as high a level as that during the World Cup final.

- Above all, I think the important thing is that the players get to feel that they need to be clear against each other in their choices, says Niklas Nordén, national team captain together with Thomas Brottman, to SVT Sport.

The game did not flow as well as he had hoped and the five had to work on finding each other in new ways.

- Body language is important, to show energy and want to have the ball, and talk during the changes, says Kim Nilsson to SVT Sport.

The goal: Silent Hartwall Arena

But to reach the World Cup final, Sweden must win tough matches along the way.

- It is very important not only to talk final, it is very tough before that.

If you look at the last World Cup, there will be penalties against Switzerland in the semifinals.

You have to find the right feeling in both group and final games, says Kim Nilsson.

December 11, 2021 is the magic date when the final team has the chance to salvage World Cup gold.

- The feeling, then, that in December we will do it together.

To make the sound level completely silent, it would be a nice feeling, says Kim Nilsson to SVT Sport.

The championship will be decided on December 3-11 and will be broadcast on SVT.
