The Belgium international is understood to be unsettled at White Hart Lane, despite only switching to Spurs from Ajax a little over two years ago.
It’s rumoured that he’s grown frustrated at the Lilywhites’ failure to qualify for the Champions League, with his snubbing of contract talks over the summer suggesting that he’s ready to move next year.
A host of clubs from across Europe have been linked with moves, and now Liverpool are in the mix, with Brendan Rodgers keen to bolster his defensive ranks.
The Reds narrowly missed out on the Premier League title last season, with their 50 goals conceded a major factor in the disappointment at Anfield.
The issues have not been repaired by the £20m addition of Dejan Lovren, who has recently been dropped from the starting XI in favour of Kolo Toure, prompting talk that Rodgers will once again make transfer moves next month.
Although direct top four rivals, Spurs may be open to a deal in January in order to bring in a decent sum for their man.
