The women's crowns beat Denmark 5–2 in the WC premiere.
Forward Hanna Olsson led the way with three goals and one assist.
The 23-year-old wants to continue to deliver as the group stage continues - against Germany on Saturday.
- Great fun to produce ahead.
But the nicest thing was getting three points, she says.
"Huge relief"
Olsson has been pulled with injury problems and is happy to deliver now.
- It is of course a huge relief to come here and deliver, with the injury background I have.
Defender Anna Kjellbin believes in a tough match against Germany, who fell 2-4 against Hungary in the first match.
- They will be very busy.
They will be hungry for revenge and we have to be ready, she says.
