This is exactly why I'm not worried about Raphinha if Barcelona signs Nico Williams. Raphinha is a very versatile player. He played as a right winger in Leeds and his first season in Barcelona. Under Xavi, he played his best football when he was moved to the AM role, where he was playing behind the striker. Last season, he played the LW and produced 56 G/A. He is a very hard worker, and wherever he is told to play, he plays it very well with all his mind. I don't think the arrival of Nico will cause him too much trouble.
I've ever seen him play as a striker, but I don't think he can excel there because he likes to run into spaces. As a striker, he will be crowded by defenders. I think he might excel as a false 9 because he moves around and presses a lot, but I'm not very sure.
Raphinha is indeed a very good and versatile player, but the question now is, who is going to be in the starting eleven and who is going to be on the bench?. I'm not sure of how flick is going to do it, but I want to believe that the Barcelona board has assured Raphinha a decent playing time before his recent contract extension. False 9 is definitely a good option, besides that was what Enrique used in winning the Champion's league, but what will be the case of Lewandoski assuming we the manager is to fit Raphinha into that position.
I want to assume that Nico won't have issues coming off from the bench, and Raphinha won't have issues playing a certain number of games before coming off, and maybe Yamal as well, because this whole thing shouldn't be tied to Raphinha alone. Well, let's see how the manager manages the whole thing for himself.
