Central Coast Mariners midfielder Mustafa Amini has agreed to a four-year deal with Bundesliga champions Borussia Dortmund, with a transfer fee likely to be reached by the two clubs in the coming weeks.
Amini's agent has told German website Bild that an agreement has been reached after the attacking midfielder impressed during a trial in March.
"Mustafa has a pre-agreement with Dortmund over a four-year contract subject to the clubs agreeing a transfer fee," Amini's agent Buddy Farah said. "The sooner it's resolved the better for all concerned. If the clubs decide for him to be loaned back that could be a good thing for him, especially from a learning point of view.
"The Mariners have been very co-operative in their dealings throughout the whole process."
The 18-year-old playmaker is expected to be loaned back to the Mariners next season in order to gain added first-team experience before heading to Europe full-time.
"Coach Jurgen Klopp told me that it was better for me if I play another year in Australia so I can prepare for the 2012 Olympic qualifiers and focus on the FIFA U-20 World Cup," Amini said. "Additionally, I can hone my skills and get more experience against quality opposition during the Asian Champions League.
"When I trialed at the club, coach Klopp treated me like a full team player and told me that I had convinced him with the way I played."
The clubs are in the process of negotiating a transfer fee after an initial offer, believed to be AU$135,000, was rejected by last year's A-League grand finalists.
Amini is currently in Gosford with his Olyroo team-mates as they prepare to meet Yemen on Sunday in the first leg of their Olympic qualification tie.
