Bertrand has excelled at Southampton since from Chelsea in 2015 after a successful loan spell and has emerged as a target for both Liverpool and City.
The 27-year-old has made more than 100 appearances for the club in three seasons and his form has seen him become a regular in the England squad.
Southampton would be reluctant to lose Betrand but would find it hard to reject a sizeable offer knowing they have capable cover in Sam McQueen and Matt Targett.
