Ah ok. Personally I don't think either would be a good career move. Liverpool have Sturridge as their established #9 and now Suarez is gone I don't see them playing two strikers, because their strength is in all their attacking midfielders - Sterling, Coutinho, Lallana etc.
And whether you think Origi is going to be something special or not (personally I don't think he was actually that good at the world cup - he might become a good striker, but not a great one), he'd still have at least a season as second choice at Dortmund, and probably more. Remember they still have Aubameyang too, who Klopp rates very highly.
