When our Jason Denayer (19) was on loan at Celtic he partnered VDV (22) for a season. I was working with a Celtic ST holder at that time, and he went to every Celtic game at home and tons away. He always insisted Denayer was the dominant partner, far superior to VD and would probably be our captain for a decade, essentially Vinny v2.0. When he was younger he'd played to a fairly high amateur level and seemed to know his onions, but it illustrates perfectly how hard it is to tell if anyone is truly elite. Btw Think Denayer was ok, capped by Belgium 35 times, now 29 and in Saudi.
