United are back in for Herrera having failed to sign the 24-year-old last summer but have seen a fresh bid for the player rebuffed by Athletic this week.
An Athletic statement read: "Athletic want to announce that they have this week rejected an offer from Manchester United, of around 36million euros (£28.85million), for the transfer of the economic and federative rights of the player Ander Herrera."
