Southampton are interested in Swansea City's England Under-21 defender Nathan Wood.
Saints manager Russell Martin is understood to be keen on a reunion with Wood, who he signed when he was Swansea boss.
But the Welsh club insist there has been no offer for the 21-year-old.
The former Middlesbrough centre-back has a year to run on his contract, though Swansea have the option to extend the deal by 12 months.
Swansea paid around £400.000 to sign Wood from Boro in the summer of 2022.
Having struggled for regular football on Teesside, Wood quickly established himself as a Swansea regular and is now regarded as one of the most promising defenders in the Championship.
