Real Madrid are reportedly interested in signing Son Heung-min this summer.
The Champions League winners are looking to bolster their attacking options following the failure to sign Kylian Mbappe, and the departures of Gareth Bale and Isco.
There are also doubts over the future of Marco Asensio, which has forced Los Blancos to look for potential additions in the final third.
According to the Daily Mail, Real Madrid have identified Son as a target, with the Spanish Champions weighing up a move for the 29-year-old.
Spurs are said to be keen to retain the services of Son, who signed a new deal with the club last summer, extending his contract until 2025.
Son helped Spurs qualify for the Champions League last season after scoring 23 goals in 35 league games.
