Southampton are reportedly interested in signing Newcastle United duo Daryl Janmaat and Tim Krul.
The Saints are believed to be in the market for a new goalkeeper following Fraser Forster's knee injury, which could rule him out of action for a year.
There is also uncertainty surrounding the future of Nathaniel Clyne, who has not been able to agree a new deal with the club despite having just one year left on his contract.
According to The Mirror, Ronald Koeman wants to bring in Janmaat as Clyne's replacement, while also sealing a deal for his Dutch teammate Krul.
