Benitez refused to be drawn on the possibility of Dutch pair Ruud van Nistelrooy and RafaelvanderVaart arriving from Real Madrid, only saying it would be "very, very difficult" to sign players this month.
Van Marwijk's side showed signs of life when Van Persie latched on to a long ball over the top and played in substitute RafaelvanderVaart, who saw his low shot pushed away before Robben fired the rebound over.
