I have known that this kind of news is a total rumor and does not have any bases and you will hardly find this kind of rumor with a reliable link. I have already the rumor in some football troll pages on the social media and I am surprised that the news has made its way into the forum. I have watched Rashford in Barcelona and I also watched him yesterday with England, Rashford is not a bad player and I am confident Barcelona will not make such type of statement. Unless they are having some financial challenges and not because of performance.
I haven't seen the news on any official page. I don't think that Manchester United needs Rashford for now, let the team stabilise first and then he can return.
