#1 Further strengthen Barcelona's formidable midfield
Barcelona's midfield is probably one of the best in Europe. Sergio Busquets' calmness and composure, Rakitic's dribbling skills, Coutinho's wonderful passing abilities and the frequent use of Sergio Roberto help Barcelona to win the midfield battle in crucial games.
With the departure of Iniesta to Kobe and Paulinho on loan to Guangzhou Evergrande, there is a gap to be filled in the midfield as these two players were crucial and regular starters for Barcelona last season. Vidal's arrival has filled the void left by the departure of these two players.
His phenomenal pace, distribution of the ball and the ability to shoot from distance are key attributes which will be greatly valued at Barcelona. He adds to Barcelona's bench strength and is also a perfect cover for Rakitic. Vidal is also a goal threat for the opposition and an excellent penalty kick taker.
Hence, he will strengthen the already formidable midfield of Barcelona with his experience and abilities.
