Montenegro youth striker appears to have joined Leeds United from Benfica.
Last year on deadline day Leeds made a quiet unannounced move for defender Amadou Haidara.
One year later they appear to have done it again, adding a high profile talent for their under-23 team.
Montenegro under-21 striker Oliver Sarkic has joined from Benfica, where he was part of their 'B' squad.

Sarkic, 20, has not joined up with his new Leeds colleagues right away as he has been on international duty with Montenegro's under-21 side.
With no official announcement, the biggest hint about the move has come from Sarkic himself.

Sarkic has a twin brother, Matija, who is a goalkeeper at Aston Villa who has just joined Wigan Athletic on loan.
He joins Ousama Siddiki, Kun Temenuzhkov and Adrian Balboa as strikers who Leeds have signed for the under-23 team this summer.
