According to Marca, Rashford still chose to transfer to Barcelona this summer and is willing to accept a significant salary cut for this.
Signing a left winger is Barcelona's priority in this summer window. Luis Dias (Liverpool) and Rashford (Manchester United) are now the focus of Barcelona. Diaz is very popular with Deco, but his value is very high. Given that Barcelona is still restricted by the "Financial Fairness Act", it is not easy to introduce him. Rashford has some advantages over Dias, one of which is that he regards Barcelona as his absolute first choice. Rashford had hoped to join Barcelona during this winter window, but now his biggest wish is to play football in Barcelona. For this reason, he is willing to accept a significant salary cut (Rashford can get about 18 million euros per year at Manchester United), and is willing to wait for Barcelona to close the window this summer.
Rashford's current market valuation is EUR 50 million, and Manchester United needs to sell him to raise funds this summer. Whether Barcelona can sign Rashford at a suitable price depends on the results of their negotiations with Manchester United.
