Sebastian Collberg has not impressed me yet.
He has only played one game in the swedish league so far.
He has made four points in six games in Frolunda's junior team.
So I can not say much about Sebastian atm.
But he has been very good in the swedish national team (U18) , 7 points in 5 games.
Pontus Aberg has played really good so far.
He has done 5 points (4 goals) on 7 games.
Pontus has been one of the better players so far in Elitserien.
I am sure that he will play WJC-20 later this winter.
