What changes could Barcelona make to their squad for the next season?

Midfielders:

(Considering that Valverde will continue with a 4-man midfield next season.)

Ivan Rakitic has been quietly impressive this season

The central midfield spots will be rightfully occupied by Busquets and Rakitic. Stats can not show what Busquets does on the pitch but surely the Spanish midfielder is the engine of Barcelona's midfield. Rakitic has been playing a slightly defensive role this season. He may not have scored or assisted many goals but this is one of his better seasons at the Catalan club.

Iniesta's departure means Coutinho is going to the wide player on the left side on the pitch whereas, on the right midfield spot we have Dembele. Both Coutinho and Dembele are highly skilled but performances have shown that Dembele needs some more time to fit in perfectly. Coutinho has created 26 chances for his team, grabbing 5 assists and 2 goals to his name in just 13 matches. Whereas, Dembele has also 5 assists in 13 matches in the league so far.

Paulinho can help out in central midfield as he has done throughout the campaign. He has been directly involved in 10 goals during the La Liga campaign. For the wide midfield spots, Denis Suarez should be selected more often.

Andre Gomes has not lived up to the expectations of the fans. Even after playing in all positions in the midfield, Gomes has not shown any signs of improvement. Gomes has no direct involvement in any goals in the Spanish League this season. Denis has 2 goals and 2 assists to his name even after playing lesser than Gomes. Barcelona will be looking to offload him in the summer.

Rafinha, who is on loan at Inter Milan should be brought back. He has been great in Itlay so far. Rafinha, being a La Masia graduate is totally aware of Barcelona's football. He should be trusted to play centrally or even on the right on midfield.

The new boy, Arthur is a great signing. His skills and technique are widely appreciated by fans all over the world. He should be kept with the first team so as to learn the Barcelona's style of play quickly.

Carles Alena, another La Masia graduate, is expected to be promoted next season from the B-team. This is surely going to a great move for the Catalan side. It will be exciting to watch a talented 20-year-old playing in the midfield.

Juan Camara's loan move should be extended for his development, Whereas, Arda Turan can be sold permanently

Changes:

Buy: Arthur (Confirmed already)

Sell: Andre Gomes and Arda Turan

Loan: Bring back Rafinha from Inter and extend Camara's loan.
