Andrea Pirlo is in, but Vidal isn't. And Vidal was just as important to Juve's Serie A-winning campaign as his Italian teammate.
They both had the same amount of assists (7), while Vidal had double Pirlo's number of goals - 5 for Pirlo, 10 for the Chilean.
According to whoscored.com, only Pirlo had a higher average rating per match than Vidal in the Italian top flight. More than worthy of a mention.
