Leeds United can confirm the signing of forward Oliver Sarkic on loan from Benfica until 31st December 2017.

Sarkic will immediately join up with Carlos Corberan's Under-23 side.

The 20 year-old, originally born in Grimsby, has represented Benfica B and also had a loan spell at Portuguese outfit AD Fafe earlier this year.

Sarkic had a trial at Swansea City during the summer and his twin brother Matija is currently on loan at Wigan from Aston Villa.
