Manchester United have launched talks with Southampton over the notion of signing defender Jose Fonte this summer, according to ESPN.
The Portuguese has been a stalwart on the South Coast in recent seasons, first joining the club over half a decade ago, though has recently been linked with a move away.
With Paul Pogba now through the door at Old Trafford, Jose Mourinho is understood to have turned his attentions to adding depth to his defence.
Despite the £30m arrival of Villarreal star Eric Bailly, the Ivorian remains relatively inexperienced at the top level. He will also travel to the African Cup of Nations in January.
There have also been doubts raised over the long-term future of Daley Blind, who was a stalwart for the Red Devils under the stewardship of Louis van Gaal.
