The Spurs boss says the Stamford Bridge club have been tracking the Croatian for 'three or four weeks', since the departure of former Blues tactician Carlo AncelottiTottenham manager Harry Redknapp has suggested Chelsea may have already made contact with Luka Modric over a potential summer transfer.
Modric expressed that he would be open to a move to Stamford Bridge this summer, but Spurs chairman Daniel Levy released a frank statement insisting the creative midfielder would not be sold.
However, Redknapp has revealed the interest in Modric from Chelsea is nothing new and has been going on since shortly after Carlo Ancelotti left the club.
"This has been going on for a while," said Redknapp, according to the Daily Telegraph. “It has been going on for the last three or four weeks since Carlo Ancelotti lost his job. Somebody else thinks he is choosing the players, not the new manager.
"Possibly [there has been an approach]. You never know. With deals now they go to agents, then the player, before the club.
"There is not a player transferred that does not know a club wants him before contact [between the clubs] is made."
The newspaper also states Tottenham may be set to report Chelsea for making an illegal approach for Modric, though club officials are still monitoring the situation.
