If Sweden reaches the semi-finals, they will, in the worst case, have to play for a bronze medal.
"For the first time in many years, you have a slight advantage in the draw. There are many players who have been around for a long time and it is now in the World Cup and hopefully at the Olympics that they will deliver, says Grahn in SVT's Morgonstudion.
Grahn points out a couple of key players and perhaps most important of all is Jamina Roberts, who for several rounds played in the Partille club Sävehof but is now a professional in Norwegian Vipers Kristiansand.
"Jamina Roberts is the shining star and the one who carries the Swedish attacking game. She is extremely important for Sweden to go far.
Grahn also points to Jenny Carlson, the center back and playmaker who will control the attacking game, who he believes will get his big breakthrough.
"Nina Koppang can be a new acquaintance"
He also thinks that Linn Blohm, who has a chronically sprained ankle, is important.
"When two-way player Linn Blohm is good, Sweden is good," Grahn said.
"Nina Koppang, 21, I think can be a new acquaintance for the audience who follow handball. She is fearless and goes on in her attitude and has a good shot, extremely important for Sweden especially when you want to change the game picture.
Grahn does not want to count out Sweden in the gold medal battle, but there are teams that are better.
"France, Denmark and Norway are in a small class of their own and have squads with a wider top.
