Tottenham Hotspur have stepped up their battle to keep Croatia midfielder Luka Modric after he was quoted on Saturday as saying he wanted to leave the Premier League club for their London rivals Chelsea.
Modric, who signed a new six-year-deal last year, was not for sale "at any price", Spurs chairman Daniel Levy said on the club's website.
"I wish to make it absolutely clear, as I have said previously, that none of our key players will be sold this summer".
"We are building a team for the future to consistently play at the highest level and retaining quality players is crucial to that".
"In respect of Luka Modric, we are not prepared to sell, at any price, to Chelsea Football Club or any other club".
"We made our stance on this issue abundantly clear in writing to Chelsea. They chose to ignore it and then subsequently made the offer public".
"For the avoidance of any doubt, let me reiterate that we shall not enter into any negotiations whatsoever, with any club, regarding Luka".
'We now consider this matter closed.' Levy said in a strongly-worded statement.
