I'd rather see Rashford go to Barcelona. It's a waste of time to stay at a club that gives no confidence in him. He may able to find his true form under Hansi Flick, and i think it's gonna be the best decision on his life.
I totally aware how Barcelona financially broken at this moment, but they're still one of best club to play for. Rashford will able to develop himself better if he goes there.
It's hard to deny an offer from Barcelona. If i were him, i go there.
With Yamal and Raphinha on the team, he'll struggle to fit in, but he's a good player with some promising talent that of Well managed he's going to be a problem. PSG was interested in him a few seasons ago, but Rashford and Manchester United both declined. They are now able to get him for a far lesser price than the previous offer if they move in.
