Vitor Roque's future is still unclear until now and even though there was previously a dispute between his agent and club management, this still does not provide further clarity on whether he will stay at Barcelona or leave. I think Barcelona should be able to keep him, especially since the funds spent to bring him from Brazil are not small.
On the other hand, Xavi is no longer the Barcelona coach and currently his control is completely held by Hansi Flick so that the previous conflict with Xavi has been suppressed. Hansi Flick must give him the opportunity to get the minutes he deserves considering his decision to join Barcelona was also part of his dream. Apart from that, there are rumors that Juventus will make an offer to Vitor Roque in the summer if he feels he no longer feels at home at Camp Nou.

His agent says that if Roque leaves it wouldn't absolutely be on loan. He would only leave on a permanent deal. He has a 7-year deal with Barcelona now. Therefore it would be quite surprising if he leaves permanently after joining in January.
Another rumour in that case is that Barcelona might go for old Real Madrid player Borja Mayoral. But I don't think it would be a very wise move. Because he has been injured for 4 months and he is expected to return by the end of the month. After a long-running injury I don't know how strong he would return.
