With tall strikers Lotta Schelin and Jessica Landstrom faltering, Sweden finally scored in the 64th minute when Linda Forsberg crossed into the middle and Therese Sjogran picked out the unmarked Dahlkvist for a simple finish from close range.
But it was Thomas Dennerby's side who made the crucial breakthrough in the 64th minute, when Linda Forsberg's left-wing cross was directed into Dahlkvist's path by Therese Sjogran and the midfielder made no mistake from close range.
