Southampton boss Ronald Koeman concedes they face losing Nathaniel Clyne this summer.

Manchester United and Chelsea are being linked with Clyne.

Koeman has not given up hope of persuading the England star to stay at Southampton, but he told BBC Radio Solent: "We know it's not easy as maybe there is some interest.

"At the moment, there is not a serious bid for whichever player in the team, but we'll do everything to keep them."
