Simons has been linked with Chelsea for some time, and the club has reportedly agreed on terms with him. But Tottenham is also interested in signing him, and the two clubs are in talks to reach a deal.
RB Leipzig, Simons' current team, has given him permission to miss training and travel to London for the talks. The German club is hoping to receive a fee of at least €65 million for Simons.
Tottenham manager Thomas Frank is leading the talks with Simons, and the club is trying to convince him to join them instead of Chelsea. Tottenham has been in good form this season, sitting second in the league ahead of Chelsea.
The club is eager to sign Simons to replace the players they have lost, including James Maddison, who suffered a serious knee injury, and Son Heung-min, who left the team.
