Southampton have set their price for captain James Ward-Prowse.
The England midfielder is ready to leave St Mary's this summer after Southampton's relegation.
West Ham, Aston Villa and Tottenham are among clubs keen.
The Sun says Southampton will seek to sell Ward-Prowse for 40m.
After their 4-4 draw with Liverpool, the midfielder said: "I've been here for 20 years and had a fantastic journey, I've enjoyed every minute of it. You never know what is going to happen in the future.
"I come away this season with my head held high knowing I've done everything I can for this club, not only this year but ever since I came through the door as an eight year old."
