Everton defender Mason Holgate is attracting interest from Southampton.
The 26-year-old, who has also been linked with Sheffield United, has been with the club since 2015 but only managed nine appearances in all competitions last season.
On their way to finishing bottom of the Premier League, Saints shipped 73 goals and the centre-back would provide a much-needed defensive boost.
The futures of Tino Livramento and Kyle Walker-Peters hang in the balance and Russell Martin will want to replace them with Premier League experience if they leave.
In addition, Southampton have completed the signing of midfielder Shea Charles from Manchester City in a deal worth £15m.
