Ander Herrera is willing to leave Athletic Bilbao for Manchester United but the midfielder will not agitate for the transfer so David Moyes must pay the full €36m (£30.6m) value of the Spaniard's buy-out clause. United had an initial €30m bid rejected on Thursday.
As the transfer window closes on Monday evening, United will have to move quickly if they are to secure the 24-year-old and finally strengthen in midfield following a difficult summer in which Moyes enters the last two days without a single major signing.
Herrera was not named in Ernesto Valverde's starting line-up for Athletic's Sunday game at Real Madrid, after the manager confirmed the midfielder's decision not to voice his desire to join United. "Ander has not refused to play at the Bernabéu, nor has he told us that he wants to go to United," Valverde said. "There has been quite a stir surrounding Ander. He is fine to play."
After the match, Valverde insisted that he expects Herrera to stay. "I left him out because I chose the players I thought were best suited to the game," the manager said. "I'm not thinking about speaking to him to convince him about anything and I'm not worried about anything else.
"I haven't spoken with the player but what I'm going to repeat is that I don't expect the club to make any moves in the transfer market tomorrow [Monday]. I do not know what will happen. I want Ander to stay with us, and that is what I think, expect will happen."
Moyes remains hopeful of acquiring Everton's Marouane Fellaini and Leighton Baines, with the manager also lining up Roma's Daniele De Rossi as a further midfield target.
