Jose Mourinho wants to bring Norwich City defender Ben Godfrey to Tottenham next month.
Godfrey has played 14 Premier League games this season and was integral to the club's promotion last season.
Football Insider says Spurs would have to pay £25m for the young centre-back.
Mourinho is looking to replace Jan Vertonghen and Toby Alderweireld, who are both out of contract at the end of the season.
