Newcastle manager Rafa Benitez is waiting to sign a new five-year contract with the club until they prove they will spend in the transfer market, according to reports.
Benitez, who will enter the season with 12 months left on his deal, is disappointed that only two players have been signed by the club this window.
He is also frustrated by the potential departures of Mikel Merino to Real Sociedad and Matt Ritchie to Stoke City.
