Allardyce, who endured a miserable seven months on Tyneside and is still angered by the way in which his Newcastle reign came to an end, does not intend to give his former employers an easy passage to Premier League survival.
He is in fact fighting for his OWN survival at West Ham, who don't look likely to renew his contract.
In theory Sunderland could be relegated instead of Hull or Newcastle, although the Black Cats are in the strongest position of the three, and the likelihood is that Allardyce could condemn the side who unceremoniously sacked him in January 2008 to their second relegation in seven seasons.
Former Magpies captain Kevin Nolan could also feature for West Ham – but Andy Carroll will not be fit for his return to St James’ Park – and Allardyce has told his players to show Newcastle no mercy.
Sam Allardyce: “We’ve (Allardyce, Nolan and Carroll) talked about it (going to Newcastle). When you look at the situation from our point of view it’s about being professional, not about what we do because it’s Newcastle and we were there.
“It’s about trying to win there for our benefit and the justification for everybody else in terms of who are fighting that relegation battle. We have to try to do our very best.
“You can’t show sympathy for anybody, because nobody shows any sympathy for you.”
Vengeance is best served cold, and Allardyce could dish up the sweetest revenge by condemning the Toon Army to Championship football next season.
