Nathaniel Clyne has been given a 10-day deadline to decide his future at Southampton, according to reports.
Saints manager Ronald Koeman has called on the Manchester United target to make a decision having stalled on contract talks.
The Daily Mail reports that Koeman is trying convince the England international to stay, with the 24-year-old also attracting interest from Chelsea.
Koeman said: "We're still speaking with Clyne and his agent, but of course we have to know in 10 days.
"The club is doing an offer the maximum what we can do and then we expect the player's answer."
Clyne's contract at St Mary's will expire in 2016.
