"I'm really looking forward to it, actually," Allen said. "I got to participate in my rookie year in the standard [AHL] format. This is going to be quite a test for us, playing against one of the top teams in Sweden. It's going to be fun to get a new experience, see a different team.
"We're definitely going to try and win that game. This is going to be a challenge to represent our league well and show them what we've got."
Allen picked up some big wins in the NHL last season after he was recalled to replace an injured Jaroslav Halak. He went 9-4-0 in 15 appearances with one shutout, becoming the first Blues rookie goalie with at least nine wins since Curtis Joseph and earning a spot on the League's All-Rookie Team.
"You just have to be patient, it's a process," Allen said on waiting for another call from the Blues. "You take it step by step. Some players can make the jump right away, but for others it might take one, two, three, four years. This is my fourth pro season now. When you do get that chance, you try to make the most of it. You get a little taste in your mouth and you want more, so you just have to be patient. The time is going to come and you make the most of it."
