Central Coast Mariners young gun Mustafa Amini is impressing in the early stage of his trial in Germany.

The 17-year old creative midfielder is training with Bundesliga outfit Borussia Dortmund and has received words of praise from manager Jurgen Klopp.

"He can definitely play football and is a really great talent," Klopp told RevierSport.de.

Amini emerged as a super talent with brilliant performances in his debut A-League season and is set to return to the Mariners when his European adventure ends in a few weeks.
