#4. Arturo Vidal to Barcelona
Barcelona were short of midfield options after the departure of Andres Iniesta and loan deal for Paulinho. However, the Catalans made a swift move for Bayern Munich midfielder Arturo Vidal and signed him on a three-year deal in the 2018 summer transfer window.
After initial interest from Inter Milan, Bayern Munich decided to sell the player to Barcelona after the Spanish giants chose to make a better offer than their Italian counterparts.
The addition of Vidal for just 18 million euros mean Barca now has a player who is good in both attack and defense.
