Tottenham are set to target centre halves in the winter, with Marc Guehi and Jarrad Branthwaite on their wish list.
The North London club are determined not to allow injuries to derail their season.
With Micky van de Ven and Eric Dier out for the moment, Spurs want to sign a defender in January.
The Mail states that two of the players they could target include Crystal Palace's Guehi and Everton's Branthwaite.
The duo have impressed in the Premier League, with Branthwaite the most likely option given Everton's financial problems.
Guehi is also wanted by other top four clubs, while Palace have no obligation to sell.
