The former Tottenham Hotspur man has been a key figure for the Black Cats this season, topping the club’s scoring charts and netting a brace in the recent victory over Aston Villa.
Speculation has been rife regarding his future at the Stadium of Light, with the Mirror recently reporting his unhappiness at the club and accrediting Premier League rivals Bournemouth with a strong interest.
Allardyce, however, has dismissed claims of any bid for the 33-year-old and hints he will only be leaving the club this month if Sunderland receive a bid they ultimately can’t say no to.
“We haven't had a bid for him, for one, and I suppose if I had had a bid for him, I'd have probably turned it down - unless it was that big a bid that the owner had told me, 'This bid is so big, Sam, that we can't afford to turn it down', and every club has that scenario,” Allardyce told the Daily Mail.
The Sunderland boss has stressed the importance of keeping Defoe at the club – even going as far as saying that he’s willing to sacrifice a particular style of play in order to get the most out of the striker.
But what the club must also take into account is their position in the table, and who they regard as their nearest rivals in the so-called relegation scrap.
Selling Defoe to Bournemouth would not only harm their chances of preserving their Premier League status, but it would also increase the Cherries’ bid to beat the drop.
