Tottenham plans to hand Heung-min Son a new deal have stalled.
The Telegraph says progress over a new Son contract has been slowed by the player's representation change.
The South Korea international forward, 28, is currently contracted to the north London club until the summer of 2023.
Son is currently the joint top scorer in the Premier League with eight goals to his name.
A new contract is expected to place Son among the club's top earners.
