Tottenham Hotspur are reportedly interested in making moves for Norwich City defender Max Aarons and RB Leipzig full-back Nordi Mukiele.
Spurs boss Jose Mourinho is believed to be prioritising a new right-back in this January transfer window as the North London club continue to concede on a regular basis in the Premier League.
Sky Sports News reports that the club are stepping up their interest in Aarons, who would be expected to cost the club somewhere in the region of £30m.
The former England youth international has made 20 appearances for Norwich in all competitions this season, and Spurs were linked with the 19-year-old in the summer after Kieran Trippier made the move to Atletico Madrid.
Tottenham have also previously been rumoured to be interested in Mukiele, who has excelled at right-back this season for Bundesliga table-toppers RB Leipzig. However, it is unlikely that Julian Nagelsmann's side will be prepared to sell one of their best players as they look to secure a maiden German league title.
