Rafael Benitez is understood to be 'deeply disappointed' with Newcastle United's transfer window, with even cheap deals proving difficult or impossible to complete for the Magpies.
In a report from Chronicle Live it is claimed that once again Benitez has been let down by his board, who failed to make a deadline day move for the signature of preferred defensive target Ragnar Klavan.
The Spaniard has hoped for some deadline day deals to ease his squad depth worries, but a move for one of his key targets has failed to materialise.
Remarkably guiding the Magpies to a top-half finish last term, the ex-Valencia and Liverpool boss has had reservations about signing a new contract in the north east.
