football is changingalso juve plays is more about pace
this will even been more in the future beside that isn't vucinic not the same level as del piero and totti
so? since when did that stop the likes of Pirlo from being great in todays football? is he blessed with pace? so what if Vucinic is not on the same level as Del Piero and Totti that is not my point, was Dario Hubner as well he was scoring double figures when he was nearly 40 hell what about Di Natale? yes fortunately for him he has pace as well as good technical abilities at his age but he is in his mid 30s and still scoring for fun.
what im saying is the typically mediteranean diet in Italy is a testamony to players still continuing to play at a high level well into their 30s and im sure if Vucinic wanted to he could do too and because his game has relied on his technical ability rather than his pace (lack of it) he could last longer than the 3 years you predicted.
Juve's style has nothing to do with pace, it is about energy and balance, if it was all about pace Pirlo would be on the bench, and Quagliarella or Matri would start every game along with Giovinco, and would never have bothered looking into the likes of Bendtner and Borriello or had even bought padoin.
