The Belgian midfielder has often been praised for performances by manager Mauricio Pochettino, who likened the player to Diego Maradona as a "genius of football".
Yet, Dembele has seemingly fallen out of favour at Spurs, losing his place to Victor Wanyama towards the end of last season.
Inter Milan put a £20m deal on the table for Dembele, who has rejected the offer of playing alongside fellow countryman Radja Nainggolan in the 'Nerazzurri' midfield.
The Italians have been busy this summer, bringing in eight players including Nainggolan and Croatian full-back Sime Vrsaljko, who stood out for the World Cup finalists.
