Peer Koopmeiners was initially torn about the potential transfer, with his feelings "a bit back and forth", according to his brother Teun. However, the midfielder has always said he would only leave AZ for something very good. Teun is satisfied with how the situation ultimately played out, with Peer extending his contract with AZ shortly after the talks with Club Brugge broke down. "He was very calm and professional about it," Teun said. "I think it's more than normal for someone in that situation." Peer will face his brother in the Europa League this season, as Juventus and AZ are paired together in the competition.
