The January transfer window is now open, with Tottenham Hotspur continuing to be linked with a host of big names.

Spurs were busy during the summer window and showed signs of troubling the upper echelons of the Premier League table earlier this season, and Jose Mourinho could look to add to his squad again in an attempt to kick on even more.

Here, Sports Mole rounds up the latest news on possible comings and goings at the Tottenham Hotspur Stadium.

Sunday morning's Tottenham Hotspur transfer talk news roundup:

Real Madrid want Tottenham Hotspur's Son Heung-min?

Real Madrid are reportedly hoping to strike a deal for Tottenham Hotspur forward Son Heung-min.

The South Korea international has formed an effective partnership with Harry Kane this season and already boasts 14 goals and seven assists in all competitions for Jose Mourinho's side.

Spurs are reportedly hoping to tie Son down to a new contract as a matter or urgency, with his current deal set to expire at the end of the 2022-23 campaign.

However, Turkish journalist Ekrem Konur claims that Real Madrid manager Zinedine Zidane has taken a liking to Son and is keen to bring the attacker to the Bernabeu in the summer.

Konur adds that the La Liga champions will soon touch base with Tottenham representatives over the possibility of a deal, although Mourinho has expressed optimism over keeping Son on the books in North London.

The 28-year-old has scored 99 goals and set up 54 more for Spurs since arriving from Bayer Leverkusen in the summer of 2015.

Zinedine Zidane wants out-of-contract trio to stay at Real Madrid

Real Madrid manager Zinedine Zidane is keen to tie Sergio Ramos, Luka Modric and Lucas Vazquez down to new deals in the Spanish capital.

The trio are all free to begin negotiating with other clubs after entering the final six months of their contracts with the La Liga champions.

Ramos and Modric are both being linked with moves to Tottenham Hotspur - where they would reunite with former Blancos manager Jose Mourinho - while Vazquez has reportedly caught the eye of Manchester United.

However, Zidane wants the trio to extend their stays at the Bernabeu, telling reporters at a press conference: "Yes, we all want [contracts to be signed].

"We want the situation to be sorted as quickly as possible. It's in everyone's interests, it would be good for everyone, so hopefully it can be sorted out quickly."

Modric, Ramos and Vazquez have made a combined total of 55 appearances for Zidane's side in the 2020-21 campaign, and the La Liga champions currently sit two points behind leaders Atletico Madrid before facing Celta Vigo on Saturday evening.
