#2 Vidal sees unnecessary red

Arturo Vidal's combustive personality means that he is always a ticking time bomb waiting to explode and we have seen traits of his tenacity throughout his career at sides like Bayern Munich and Juventus.
However, since arriving Barcelona, the Chilean international has mellowed down and is currently playing some of the best football of his career this season, with his advanced role leading to more goals and attacking returns.
The absence of Luis Suarez and Ousmane Dembele saw Vidal deployed in a front three alongside Messi and Griezmann and like most of his teammates, Napoli's effectiveness meant that he remained on the periphery of the game.
Perhaps the frustration got to him, leading to a rash challenge on Mario Rui late in the game and despite clearly hacking at the Spaniard and missing the ball, Vidal made light of the tackle and urged the Napoli man to get to his feet.
This prompted a scuffle between the two, leading the referee to issue both men a yellow card and coupled with the initial yellow for the tackle, it means that Vidal would now miss the return clash in Spain.
