The England star’s career in north London is hanging in the balance after a poor season following his World Cup heroics.
Trippier, 28, has been the weak link in Mauricio Pochettino’s side this campaign with an own goal against Chelsea and a missed penalty against Crystal Palace in the FA Cup just two of his worst moments, while injuries have also harmed his form.
This hasn’t deterred his suitors, according to Gianluca Di Marzio, though with Man United keen to add to their ranks at full-back with Antonio Valencia leaving this summer and Diogo Dalot still only 20 years old.
Napoli, meanwhile, may well be protecting themselves should they lose Elseid Hysaj, although they do already have Kevin Malcuit in their ranks to replace him.
