In an interview with hockeysverige, Hagelin said that playing on a bigger ice surface will help his play, "I can clearly become more aggressive when I play. Already in the next game, I hope that that particular piece will be a little better. - The surfaces you get when the rink is bigger makes you you can get wider the zone which should suit my skating pretty good. I noticed this evening that it was possible and use just that quite well."
