Williams was a key target for Madrid's rivals, Barcelona, last year, but the player eventually decided to stay in Bilbao. Despite his rejection, the 22-year-old remained a key target for the Blaugrana until as recently as this week, when club president Joan Laporta told TV3: "He was one of the candidates last summer, we were evaluating [Dani] Olmo and Nico. We have a good profile of this player, who is an excellent player, but I think at this moment we are evaluating other options."
