Barcelona is reportedly not only processing Rashford's arrival. I also read a news article that Barcelona is also interested in signing Rodrygo from Real Madrid. I don't know if this rumor is true or not, but if it is, I think it would be very exciting. Because Rodrygo's position is currently slowly being replaced, so I don't think a move to Barcelona would be a problem. Who knows, maybe he'll shine again at Barcelona. However, Rodrygo hasn't responded to this rumor so far. This indicates that Rodrygo still wants to stay at Real Madrid.
What!! Barcelona interested in Rodrygo? I haven't read this rumor but I'm sure it's just a rumor from some shady media outlet. The reason is Real Madrid might not agree to a loan deal and even if they do it's likely to be to another club. They only want to sell for their asking price, which is 100 million. With this in mind how can Barcelona spend that much money when their finances are so unstable? And I've heard that Barcelona main focus right now is Luis Diaz, who could have a lower release clause.
Barcelona wouldn't dare go for Rodrygo, because they don't have such amount of money to spend on one player. We saw how they couldn't get Nico Williams due to their financial challenges. As for Rashford, it's clear that he will be on his way to Camp Nuo soon. I can't say if signing Luiz Diaz is not also a rumor but let's watch and see what happens next. Fingers crossed.
