Robb spent two injury hit years at Tannadice, having moved there in 2006 from rivals Dundee. If he can keep himself fit he should be a decent signing as he has a bit of pace and a decent cross. His preferred position is on the left wing, but it seems he can play at left back if required.
Robb joins Jack Ross, Tom Brighton and Dennis Wyness in signing for us this summer, and there should be a few more players arriving in the coming weeks.
