And his one simple reason for backing the Wearside outfit? Sam Allardyce.
Indeed, the 61-year-old is a proven specialist when it comes to keeping teams away from the relegation zone and, while this could be his biggest challenge yet, Allardyce has shown signs of his usual tact at the Stadium of Light.
Pearce told Sky Sports News on Monday morning: "I’ve always thought they’ll stay up for the one reason that Sam Allardyce is in charge.
"They could stay up at the expense of a Swansea, a Bournemouth or a Norwich."
It's a surprisingly confident statement from Pearce considering the fact Sunderland are currently four points from safety. They had also lost four on the bounce before beating the only side in a worse position than them in the Premier League table.
Before Big Sam arrived at the Stadium of Light, however, plenty saw him as the perfect manager to keep the Black cats up.
In many ways, Allardyce is the perfect manager for any relegation scrap. There have been chinks in his armour so far yet, at the same time, he's got Sunderland winning far more than anyone could have envisaged when they were struggling under Dick Advocaat - who just seemed exhausted by it all.
