Tottenham are demanding Anthony Martial in Manchester United's offer for Toby Alderweireld.
The Sun says Tottenham chief Mauricio Pochettino is ready to let the Belgian go after an injury-plagued season at Wembley but Spurs are determined to drive a hard bargain, valuing Alderweireld at £70m-plus.
The Londoners know they need to sell now to prevent Alderweireld being able run down his contract or use a clause to move for just £22m next summer.
And if any deal is on the table, Tottenham are ready to make their own move for France ace Martial, who has fallen down the United pecking order under Jose Mourinho.
Poch is keen on landing Martial, who has always impressed against Tottenham with his pace and versatility.
