The 22-year-old was a regular starter for Hansi Flick’s side last season, making 42 appearances across all competitions, and laying on three assists.
However, as the Catalan giants remain in a delicate financial situation, they are reportedly open to selling him to raise funds for more incoming transfers.
Barcelona have already brought in Anthony Gordon, Karim Adeyemi and Rodri this summer and they could still make a late push for Julian Alvarez.
Balde has previously confirmed his desire to stay at the club and sign a contract extention beyond 2028.
However, reports in Spain indicate that stance has changed, with Jijantes claiming he's ready to move on following talks with Flick over his place in Catalonia.
Balde has been left unconvinced over his long-term spot in the starting XI, and Manchester United could table an offer in the region of €50m as they look to bolster at left-back.
Mundo Deportivo are taking a different angle - stating he will only leave if Barca push for an exit - as his preference is to remain in Spain.
