Champions League finalists Borussia Dortmund confirmed on Thursday they have signed Gabon striker Pierre-Emerick Aubameyang from French Cup winners Saint Etienne on a five-year deal.
"We're pleased to have got our dream signing in Pierre-Emerick Aubameyang," said Dortmund's director of sport Michael Zorc.
"He's extremely versatile in the forward positions, has exceptional speed and is a real goal-threat."
The 24-year-old scored 19 goals and created 14 assists as Saint Etienne finished fifth in the French league last season, while Zorc says he can be used on either wing or up front as a striker.
Neither club have revealed the transfer fee as Aubameyang, reported to have cost 13 million euros ($16.8m, £11m), becomes Dortmund's second new signing after Greek defender Sokratis, who cost 9.5 million euros from Werder Bremen.
"Our plan is not to play football in the shadow of Bayern Munich, we want to be stronger than last season," said Borussia coach Jurgen Klopp, referring to Bayern winning the treble of European Cup, league and domestic cup last season.
Aubameyang helped Saint Etienne win their first trophy for 31 years last season and has made 30 appearances for Gabon.
Dortmund are in training at Kirchberg, Austria, until Saturday and take on Bayern in the German Super Cup final on July 27, while CEO Hans-Joachim Watzke has laid out their goals for next season.
"We want to qualify for the Champions League again (meaning a top four finish in the German league), to qualify from the Champions League group stages and go as far in the German Cup," said Watzke.
Poland striker Robert Lewandowski, who has openly admitted he wants to leave Dortmund, returns to training from his honeymoon next week and Klopp has called on Borussia fans to show him some respect, despite his want-away position.
"What has happened except he has said that he would like to change clubs?," said Klopp, with Lewandowski under contract with Dortmund until June 2014.
"Just because we see the club as the only one to play for, doesn't mean that every player feels the same way. You have to respect that."
