After this weekend's second place in a challenger tournament in Belgium, the younger Ymer brother, Mikael, moved up to 60th in the world ranking and had a strong tournament.
And already this weekend the Davis Cup awaits.
- There is something about the energy, especially when we play at home, there is very high pressure.
It is probably a form of energy that does not normally occur.
It means everything.
Since I was little, I've been watching the Davis Cup, so it's great to be back, says Mikael Ymer.
"Extra special"
The brothers have been successful together before.
During the Stockholm Open 2016, they won the doubles class - now they can form a pair again.
- It feels extra special, it's a family dream.
Dad took us to Lidköping when Robin (Söderling) played when we were very young.
Something has been built up there, says Mikael Ymer.
Brother Elias is on a similar track.
- That's what we got up and trained for, one day that's what we hoped for.
Dreams can come true sometimes, says Elias Ymer.
In addition to Mikael and Elias Ymer, the selected men's squad for the Davis Cup consists of André Göransson, Karl Friberg and Leo Borg.
"It will be the riddle"
Before the tournament, the brothers have been working on their "secret" tactics.
- Some offensive patterns...it's so detailed it would be like Chinese.
We keep it a little bit to ourselves, we let the people see if they can find them.
That will be the riddle, but generally the position in the track, says Mikael Ymer.
Sweden hosts Bosnia-Herzegovina on Friday and Saturday and the international matches are broadcast on SVT.
- They have skilled players.
I think we have good chances, Sweden always does, says Mikael Ymer.
