Tottenham Hotspur are interested in two defenders from the Bundesliga.
Spurs boss Antonio Conte wants to bolster his defence this summer.
Conte is specifically looking for a left-sided centre-back.
The Athletic says the Italian is looking at RB Leipzig star Josko Gvardiol and Nico Schlotterbeck from Freiburg.
20-year-old Gvardiol is still under contract until 2026.
Borussia Dortmund is also looking at Schlotterbeck.
