Real Madrid star Luka Modric has been approached by a number of MLS clubs in recent weeks, but it remains unlikely that the Croatian midfielder will leave the Santiago Bernabeu in the near future. 

Modric has been a key figure for Los Blancos since his move from Tottenham Hotspur in 2012, and the 34-year-old's current contract will keep him in Madrid until 2021.

But ESPN reports that American clubs D.C. United, Inter Miami and Atlanta United have all shown an interest in prising Modric away from the Spanish giants in the January transfer window, as the MLS looks to bolster its brand by landing another superstar

D.C. United had opened initial talks with the 2018 Ballon d'Or winner and his representatives, but it quickly became apparent that his hefty wages would make a move to the MLS extremely complicated. 

Despite being crowned the best player on the planet only 12 months ago, ​Modric is no longer a guaranteed starter in Zinedine Zidane's midfield, following the emergence of Uruguayan youngster Federico Valverde.

The 21-year-old has been a regular in the heart of Los Merengues' midfield, making 15 league appearances and scoring two goals in the process. Valverde's sudden burst onto the scene has forced Modric into occasionally settling for a place on the bench, and given his advancing years, he is unlikely to extend his stay in ​Madrid beyond 2021.

The playmaker is believed to be interested in a move to the MLS in the longer term, and his stature in the game would make him a marquee signing for any Major League Soccer team. 

Modric scored his third league goal of the season against Getafe on Saturday, as Zidane's men cruised to a 3-0 victory over their hosts. Madrid sit joint-top of La Liga with rivals ​Barcelona, and they face Valencia in Wednesday evening's Supercopa de Espana semi-final, with the possibility of taking on la Blaugrana in Sunday's final.
