Vidal is one of the most important players for both Chile and three-times Serie A champions Juventus. He's a force of nature on the pitch, posting one of the highest tackle rates per game of any player in the world, but has he always been this good?
As you can see from the gif below, not quite. 2010-11 is when we first see that he's both a scorer and a strong ball winner in midfield, while 2012-13 was what really got him recognition as one of the most complete midfielders in the world. This past season, you can see a small drop in most of his stats. Whether that's a result of the knee injury he picked up that needed surgery before the World Cup, or simply a difference in tactics is unknown.
Whatever the case, Chile need him to be his usual dynamic self to stand a chance of getting past Brazil today.
