According to Area Napoli, the club are looking to cash in on the 31-year-old, and have apparently offered the Belgian international to Maurico Pochettino's side, who still has two years left on his current contract in Naples.
Mertens was a key part of the Napoli side that narrowly lost out to Juventus in the race for the Serie A title, scoring 18 goals and providing six assists in 38 league games, although it's some way off last season's stats of 28 goals and 11 assists in Serie A during 2016/17.
A name that is bound to excite Spurs supporters, here are how they reacted on social media after being linked with Mertens.
Currently part of a Belgium squad that have reached the semi finals of the World Cup, scoring once and providing an assist, a striker with the quality and experience that Mertens has would be ideal.
With Pochettino failing in the past to add quality support to take the pressure off Harry Kane in the shape of Vincent Janssen and Fernando Llorente, Mertens could be the player to do just that, while his versatility to play in a number of positions is an added bonus.
