Yes, apparently there were some player changes when Hansi FLick became their coach. And because of financial issues too, Barcelona will definitely make the quite difficult decision to sell some of their top players first and bring in players who suit Flick and also suit the budget they have. One of them is that they want to sign Joshua Kimmich.
But there is no final decision yet regarding who will be sold later. And it is even rumored that Lewandowski will be sold by Barcelona, but that is still a rumor because after all, their new coach is Hansi Flick, who is certainly familiar with this player. And what's more, Lewandowski also hopes that he will stay at Barcelona.
I believe some of Barcelona players will be sell this summer because they really required fresh funds to bought the players so before buy some players Barcelona have to sell some players first but until now there is still no confirmation which players will be on Barcelona's sell list and so far the current news it just a rumour but several months ago Raphinha rumoured will be sell and i know he performing well with Barcelona this season but Barcelona still considering to sell him because they are confident that Raphinha's price will be quite high and they can use the money from the sale of Raphinha to buy new players
Some people believe why Barcelona pertormance was decline last season is because they were lost Sergio Busquets so losing this player is greatly affect to Barcelona performance and Hansi Flick this summer want to focusing to find the player who can be played as holding midfielder just like Sergio Busquets and Hansi Flick feel Joshua Kimmich could be the right player who can replace Sergio Busquets position as holding midfielder but it won't be easy to gets Joshua Kimmich from Bayern Munich because Barcelona have to compete with Real Madrid and Arsenal to gets him
