The 24-year old midfielder was reportedly close to joining Manchester United in the summer but a deal fell over before the deadline.
It is believed that United, along with some other clubs, will pursue Herrera in January but Urrutia says Bilbao are in no mood to sell.
"I don't know what other teams will do, but I consider the Herrera issue to be closed," Urrutia told a press conference.
"Ander has a contract until 2016. All players have to focus on giving Athletic all you can give."
