Sunderland boss Roy Keane is chasing Celtic defender Darren O'Dea.

The Daily Record says the Irishman has been alerted to the fact his 20-year-old countryman has failed to start an SPL game this season.

Keane has already raided Celtic for Ross Wallace, Stan Varga and Liam Miller and failed in a bid to snatch outcast Bobo Balde in the summer when the player opted to stay at Parkhead.
