United failed with a late bid to sign Herrera at the end of the last transfer window.
Reports have suggested that United boss David Moyes is ready to rekindle his interest in the midfielder in January.
Urrutia told a press conference: “I don’t know what other teams will do, but I consider the Herrera issue to be closed.
“Ander has a contract until 2016. All players have to focus on giving Athletic all you can give.”
