I am sure Barcelona would not take a permanent deal as they have eyes on Luis Diaz, Nico Williams and Rafael Leao as their main target in the summer window.
They will not make a permanent deal for Rashford because they can't afford it at the moment. Even the loan deal will cost them some serious money. So, there is no point chasing Rashford now if they are more keen on other talents. It is going to be expensive.
Deco[FC Barcelona Sporting Director] had a meeting in Lisbon with Rashford agent so there is a possibility it could happen, but it will depend on the departure of Eric Garcia or Ansu Fati so nothing can be ruled out yet and I agree it will to expensive concerning the wage bill of Rashford, but since Barca are having this talks they might have a solution.
