Manchester United have given Tottenham short shrift following an inquiry for Anthony Martial.
Martial's agent revealed earlier this month the 22-year-old wants to leave United but the MEN understands the club has quoted Tottenham 'silly prices' for a player they signed for an initial £36million in 2015.
The fee for Martial rose to £44.4m last year after his 25th United goal against Burnley triggered an additional £8.4m payment. United agreed a fee rising up to £56m with Monaco and value Martial well in excess of that figure in the current market.
United's brusque response to Spurs was inevitable after the two clubs failed to reach an agreement in talks over Toby Alderweireld. United opened negotiations with Tottenham in May with the intention of concluding a £55m deal for the 29-year-old but Spurs are holding out for considerably more.
Sources say Martial and Alderweireld's situations 'could rumble on and on', with the Belgian refusing to sign a new Tottenham contract.
The transfer window for Premier League clubs to sign players closes in six weeks' time on August 9.
Despite United's stance, Jose Mourinho has said his policy is that if a player agitates he 'will never stop a player from leaving even if it is to a rival'. Mourinho said the Alexis Sanchez and Henrikh Mkhitaryan swap deal was proof Premier League top six clubs should conduct transfer business between each other more often.
Both Alderweireld and Martial are technically out of contract next year but their deals include one-year options. Alderweireld's extension would automatically trigger a £25million release clause in 2019.
Spurs coach Mauricio Pochettino's admiration of Martial dates back to three years ago and just before he joined United on transfer deadline day.
Martial signed a new contract with Monaco earlier that summer amid interest from Spurs but United saw off competition from Chelsea to sign the France international.
United have prepared for Martial's possible departure, having held informal talks with Chelsea winger Willian's representatives in May. They also hold a long-standing interest in Real Madrid's Gareth Bale.
Martial's agent, Philippe Lamboley said earlier this month: "After thinking about all the possibilities, Anthony wants to leave Manchester United. When Manchester United, which is the most powerful club in the world, does not find an agreement in eight months of negotiations, it is that it does not really want to make him an important player."
"It is a well-considered decision. He is under contract, United will have the last word and we will respect the decision of the club, it will go to the end of its commitment.
"We do not have the same vision on Anthony's future. Without the unconditional support of the fans, Anthony would have already asked to leave United.
"I will not comment on the consequences of the January transfer window. Everyone will have his opinion, I think he must resume the course of his career. The time has come."
