Millwall are among a number of Championship clubs who are reportedly interested in signing Crystal Palace midfielder Owen Garvan.
The 26-year-old has one year remaining on his current contract at Selhurst Park.
Garvan spent the second half of last season on loan at Millwall after being omitted from Palace's 25-man Premier League squad.
The Eagles are now thought to be considering selling the former Republic of Ireland international, according to Sky Sports News.
Garvan joined Palace from Ipswich Town in 2012.
