I'd have to say Sellars. Stood on the terracing as a lad watching Scottie weave his magic with that left foot. Definately not the best left sided player we've had but he stands out for me cos of the memories l have of him terrorising some poor right back. Others would have to be Tugay, Shearer, Duff and 110% Hendry who still gives it everything after watching The Match on Sunday)
