The veteran striker could be set for speedy exit from the Stadium of Light.
The 33-year old had a mixed first season with the Black Cats – scoring four in his 19 appearances – but he already has five to his name this campaign, albeit three coming in the League Cup win over Exeter City.
At the age of 33 Defoe is approaching the tail-end of his career however, and the Sunderland hierarchy will not stand in his way should an offer come in for him according to the Telegraph’s report.
Bournemouth are thought to be monitoring the situation and could well move on their former frontman, with Allardyce keen to use any potential incoming funds to bring in another striker deemed more suitable for the task of firing the Black Cats to safety.
Steven Fletcher’s performances for Scotland recently, and his suitability in leading the line, has likely placed him ahead of Defoe in Allardyce’s mind – as evidenced by the latter's inclusion amongst the substitutes against West Brom on Saturday – and a departure could make sense for all parties should his game time become limited over the next few weeks.
