Southampton manager Ronald Koeman has warned Jack Cork that he has a week to sign a new contract at Southampton, or face leaving the club.
Cork, 25, has a deal which expires in the summer and has yet to accept the offer of new terms.
Koeman told reporters: "We are still waiting about the answer of Jack and we like to know it next week.
"If Jack likes to stay I'm very happy, if he likes to move then that means that we need another midfield player."
Southampton are currently third in the Premier League, 10 points behind leaders Chelsea.
