Tottenham Hotspur have been linked with the likes of Nikola Milenkovic and Sven Botman.
According to Italian journalist Fabrizio Romano, the London club are keeping tabs on both defenders and they could make a move at the end of this season.
He said: “Milenkovic is an interesting situation because his contract expires in two years. At the moment he doesn’t want to extend his contract and Fiorentina knows that he wants to move.
“Let’s see if Tottenham will go for him or not, but for sure he’s appreciated. At the moment he’s not the first choice, but he is appreciated.
