It was already clear that Rashford would go to Barcelona, the whole issue is in registration and now, as I understand it, there is no progress there. The deal for Pau will definitely not be very significant, the entire transfer costs 15 million - as much as Rashford's salary. As I understand it, they need to follow the 1:1 rule regarding salaries, so in order to register Rashford, they need to release players who collectively earn as much as he will earn. In general, Barcelona faces a difficult puzzle.
Ter Stegen + Pau Victor being sold could have fixed it.
Although i heard Ter Stegen's will be undergoinganother surgery , but still doesn't change much for now.
Although, I've heard that if an injury spans beyond four months, it could create room for a signing like Marcus Rashford, especially with Pau Victor also on the line... But Ter Stegen himself mentioned a three month recovery. This could be a twist though as there're no official announcement from Barcelona yet, but they might declare a longer period to qualify it as a long-term injury IMHO
