#3. Arturo Vidal
When Barcelona unveiled Arturo Vidal as their new signing during the summer transfer window, many eyebrows were raised. But the former Bayern Munich star knows how to put his critics in their place, burying every doubt that accompanied his transfer with a couple of scintillating displays at the Nou Camp this season.
As a matter of fact, the signing of the Chilean midfielder will do Barcelona a lot of good, especially in the UEFA Champions League, with the player himself having revealed on multiple occasions that his priority is to win the continental prize at the Nou Camp.
A highly experienced superstar with an incredible fighting spirit, Vidal would be a perfect match against any elite team in the European tournament. His immense physicality also means that he can help the team to avoid bullying from physical teams, such as the one that happened against Roma last season.
