Tottenham Hotspur are keen on improving their defensive options at the end of this season and they have identified Southampton centre back Jannik Vestergaard as a key target.
According to the Express, the Londoners have now stepped up their bid to sign the player after the poor defensive showing against Newcastle United.
Apparently, the 28-year-old centre back could cost around £18 million.
The London club have been linked with the likes of Milan Skriniar as well and they are expected to go back with an offer for him at the end of this season.
