Flick is adamant in his request for an attacking wide player to join the team, and after encountering resistance from Athletic Bilbao regarding Nico Williams, he has put forward Marcus Rashford as a potential target for the Barca board.
Spanish journalist Albert Fernández, who works for Gol Play, states that Flick has proposed the immediate signing of Rashford.
However, it is unclear whether Barcelona have contacted United to discuss a transfer.
Rashford, 26, is tied to the English giants until the summer of 2028.
