The first thing is that João Félix is still young. He is only 23 years old. He has a long career ahead of him. If he stays with La Liga's best team Barcelona this time around, he'll be able to sort himself out quickly. He can solve his own problems. and become more experienced. As a result, we may see more excellent performances from João Félix in the future.
But now João Félix has been added to the squad only as a replacement for Lewandowski. If Lewandowski is injured, João Félix will have a chance to prove his ability. Let's see how this youngster performs with Barcelona.
firstly, maybe Xavi will try this young player first in a few matches and if Joao Felix makes an improvement in Barcelona performance I'm sure even though he is currently on loan from Atletico madrid, he is a reliable player and can make a good contribution to Barcelona winning the title in La Liga. all of this just speculation, Im not sure I will be a major player at Barcelona, but what is more certain, Xavi will certainly always consider wisely and the reason for borrowing Joao Felix is that there must be a very good purpose for this team.
