Collins has been a target for Sam Allardyce since he took charge of Sunderland, and a report in the Mirror has indicated that he would be open to moving from West Ham to the Stadium of Light.
The 32-year-old is out of contract at the end of this season, and it is apparent that he will not be offered a new deal to stay at the Boleyn Ground.
Collins himself is in no rush to leave West Ham, but with his future at the club under threat, he would be open to moving to Wearside in January to ensure his playing situation remains in the Premier League.
However, it would take a big paying contract to tempt him to link up with Allardyce, who he played under at West Ham.
Collins wants assurances about the value of his contract as he would be signing for a club in the midst of a relegation battle, although the club’s current form does mean that the centre-back is almost guaranteed first-team football.
Allardyce has seen his team struggle in the defensive zones this season, and he wants to sign Collins as he is a proven Premier League player, and one who will add experience and stability to a team who look out of sorts.
