#2 Departure of Rakitic, Rafinha and Denis Suarez
Currently, FC Barcelona have numerous talented midfielders: Arthur. Busquets, Rakitic, Vidal, Rafinha, Denis Suarez, Alena, Samper, Puig and Oriol. De Jong's arrival would further overstack the midfield options and obviously some players need to be offloaded.
The midfielders most likely to leave the club because of de Jong are Rakitic, Rafinha and Denis Suarez. Both Rafinha and Suarez have been recently been linked with a move away from the Camp Nou because of lack of playing time. Rafinha is, as of now, injured and will only move in the summer. Suarez has been linked with a loan move to Arsenal but the clubs haven't been able to agree on terms which means that a January move, as of now, looks highly unlikely. So, both Rafinha and Suarez are expected to call time on their Barcelona careers in the summer. The surprising inclusion is none other than Ivan Rakitic.
Rakitic has unquestionably been one of the most consistent players in the team and should be lauded for his commitment to the club. However, it is also evident from his playing style that he is not suited to the positional play at FC Barcelona. Moreover, with age not on his side, there isn't much scope for molding him. So, the arrival of de Jong surely means that Rakitic's time at the Camp Nou is coming to an end.
