Rashford will only replace Raphinha if Raphinha has fitness problems because it is clear that Raphinha will not be replaced when he is fit, but initially I thought that in this match when Lewandowski was not in the list, his position would be replaced by Rashford because he could also be placed in that position, but Torres' name came out as a starter, maybe Flick still didn't trust him enough. What is clear is that this match was a good start for Barcelona because they won very easily.
I also thought that we will see raphinha in the squad as a replacement for lewandowski in this match. But Hansi Flick is not willing to rely on Rashford. We have seen Torres in the starting XI. And Torres has performed quite well. Rashford came on as a replacement for Torres in the 69th minute. But , if Rashford was given a chance in this match, he would have had a chance to adapt himself better to the Barcelona squad. Rashford can be considered as a replacement for Lewandowski. But Hansi Flick probably does not like Rashford's style of play.
