(CNN) -- If Saturday is any indication, Borussia Dortmund won't miss Mario Gotze. Pierre-Emerick Aubameyang, brought in to beef up the attack after Gotze was sold to rival Bayern Munich, netted a hat-trick on his Bundesliga debut as the league and Champions League runner-up began by beating Augsburg 4-0. If he continues to impress, his $17 million transfer fee -- Aubameyang joined from Saint-Etienne in July -- will be considered a bargain. The Gabon international finished second in goals in Ligue 1 last season and was fifth in assists. He opened the scoring with a header in the first half and added two right-foot finishes in the second to become the sixth player to register a hat-trick in his Bundesliga opener.
