The Black Cats' survival is still not guaranteed, despite Allardyce having taken over in October.
Allardyce took the reins at the Stadium of Light in October, when the Mackems were second-bottom of the Premier League and without a win to their name.
The 61-year-old has developed a reputation as being something of a top-flight fire fighter, having saved Bolton Wanderers, Blackburn Rovers and West Ham United on various occasions this century.
While he also boasts an impressive record of never having been relegated as a Premier League manager.
But despite taking 27 points from his 25 matches in charge of Sunderland, Allardyce has been unable to steer the Black Cats away from danger.
However, the Wearside club are now only a point away from safety with a game in hand after beating Norwich City 3-0 on Saturday.
But has it been worth it so far?
"It’ll only be worth it if we stay in the Premier League," Allardyce told the Alan Brazil Sports Breakfast show on Tuesday.
"It’s a fantastic club. I think the supporters are outstanding, they’ve stuck by the team all the way through. The facilities here are second to none.
"It’s so passionate about football and I’m a football man.
"So I’m very, very happy but I’ll only be happy and satisfied if we’re in the Premier League next season."
Sunderland face third-place Arsenal on Saturday, ahead of fixtures against mid-table quartet Stoke City, Chelsea, Everton and Watford.
