Berra is out of contract at the end of the season and as yet there have only been tentative talks held over a possible new deal
The Scotland international was placed on the transfer list at the start of the season after asking to leave Molineux.
Stoke, Swansea and Wigan are all thought to be admirers of Berra and they are weighing up moves for the central defender when the transfer window reopens in January.
Wolves could decide to cash-in on Berra in January rather than risk losing the talented stopper for nothing at the end of the season
The 27-year-old joined Wolves from Hearts in January 2009 for a fee of around £2.3m and has made over 100 appearances for the Championship side.
