Sunderland have had eyes on Collins ever since Sam Allardyce took over, and the 60-year-old is reportedly very keen to snap up the experienced defender, having had a chance to assess his squad.
The Black Cats are, reportedly, expecting to have a quiet winter transfer window, but Allardyce would like to bring in some defensive reinforcements.
And the former Blackburn Rovers manager feels that Collins would be the ideal candidate to come to the Stadium of Light.
Collins and Allardyce worked together at West Ham, and the Sunderland boss remains a fan of the commanding defender’s talents.
Collins has had limited game time for the Hammers this season, and there is a feeling that Slaven Bilic could be willing to listen to offers for the Welsh international when the transfer window opens.
Sunderland have conceded 26 times in 13 matches so far this season, leaving Allardyce determined to tighten their backline.
