This season Serie A has been great to watch, not perfect and still big divisions between clubs but the notion that its defensive, side to side and slow isn't accurate. Juve has been nothing short of fantastic this season and their performances in CL shows a) their quality and b) they play a very attractive high tempo game with Alves pace instrumental in that.Serie A is very different in terms of its physicals demands - main reason why Evra and now Alves have managed to prolong their careers
There is no denying that his age will no doubt limit his playing time, mainly driven by recovery time, hence if he's rotated well he can still be a highly effective player IMO
