LEEDS midfielder Rudy Austin and Newcastle United wing back Shane Ferguson are two names on Millwall's January radar.
Boss Ian Holloway is open to strengthening every position in his squad and tough-tackling Austin, 29, would add much-needed bite to the Lions' engine room.
The Jamaican is out-of-contract next summer and is understood to be close friends with Den striker Ricardo Fuller, who could persuade him to move to South London.
Ferguson is left-sided and can play in defence or on the wing.
The 23-year-old Northern Ireland international spent time on loan at Birmingham City last season and Millwall could take him on a similar short-term deal.
Brighton were linked with a move for Austin last month while NewsAtDen understands that Celtic have also expressed an interest in Ferguson.
