Hungary defender Roland Juhasz is being watched by Sunderland.
The Daily Mail says Sunderland have added Juhasz to their list of defensive targets for January.
Manager Martin O'Neill has shown interest in Manchester City's England centre half Joleon Lescott and Sylvain Distin of Everton but neither are keen to move to the North East.
Towering centre back Juhasz, 29, is available on a loan from Belgian side Anderlecht.
