I never really rated him, because he is a goal waster.
But at least i expected him to be better than Quaq (before Quaq joined Juve i never really rated him either)
However at this point it is safe to conclude that Quaq is much better player overall.
At this time last year Quaq has shown more promise and more essence, being a better creator, a better assist-man and a better finisher.
Faster and more technical than Vucinic.
Vucinic is taller and thats about it, hopefully, he will be more stable as well, because that was Quaqs greatest weakness.
