Sydney youngster Alex Gersbach is set to sign with Norweigan giants Rosengorg on a three and a half year deal, pending a medical.

โ€œAlex is a very ambitious young man and I would like to thank him for his service to Sydney FC,โ€ Sydney coach Graham Arnold said.

โ€œIt is always pleasing to be able to bring through a young player, develop him and see him get a great chance in Europe. We would have loved to have kept him for another year, but it's a great opportunity for him and I wish him the very best for the future.โ€

The talented 18-year-old defender has made 31 appearances for the Sky Blues since making his debut in late 2014.

Gersbach flies out of Australia on Monday.
