Barcelona only take benefit from his loan status, and ditching Raphinha would be the club's biggest mistake. I have my doubts about Rashford, he is the type of player who is lazy to work hard, always waiting for a pass, not suitable for Barcelona's style of play which is all active in carrying out roles. For that Rashford will have a hard time if he stays with his poor playing style.
Raphinha and Yamal are in their best form now. An experienced coach like Hansi Flick will never make a big mistake like leaving these two players out of the squad. I can say for sure that Yamal and Raphinha will be in Barcelona's starting XI.
Barcelona's contract with Lewandowski is going to end next season. Now Barcelona is looking for a worthy replacement for Lewandowski. And I think that is why Barcelona is going to bring Rashford to the squad on loan. Hansi Flick will experiment with Rashford this season. And if he can adapt himself well to Barcelona's squad, Barcelona will decide to buy Rashford. And FLick will probably try to use Rashford as a replacement for Lewandowski. I guess Hansi Flick is probably going with this plan
