Wolverhampton Wanderers have transfer listed Christophe Berra and Adam Hammill, according to the Shropshire Star.
Berra, who has played 111 league games for Wolves since signing in 2009, has asked to leave the Midlands club. The Scottish centre-back is on the final year of his contract and has "decided to seek a fresh challenge elsewhere".
Meanwhile, 24-year-old winger Hammill is up for sale after making just 10 league starts for the recently-relegated club since signing from Barnsley in January 2011.
Hammill spent the last few months of last season on loan at Middlesbrough.
