With Gus Poyet leaving Sunderland this afternoon, Allardyce is reportedly being lined up as a target to replace him.
Allardyce represented Sunderland during his playing career and the thought is that he would take the job at the Stadium of Light should it be offered to him.
Allardyce has never won over the fan-base at West Ham and he would be hoping that Sunderland's supporters would be more willing to support his favoured style of playing.
Hammers supporters have complained about the lack of entertainment on offer at the Boleyn Ground in recent times, but Sunderland are desperately in need of results - something which Allardyce has proven himself to be very good at throughout his career.
The Black Cats are only narrowly above the drop-zone and should Allardyce join them before the end of the season his first task will be to ensure that they stay in England's top flight.
