The Dane believes the former West Ham boss will keep Sunderland up.
Sunderland are once again in a relegation battle at the wrong end of the Premier League table.
The Black Cats are currently in 19th position in the Premier League on just 12 points from the opening 15 games.
Until recently, it was even worse. Sunderland were way off the pace until recent wins against Crystal Palace and Stoke City took them briefly out of the relegation zone.
The upturn in form has been caused by the appointment of Sam Allardyce at the Stadium of Light.
He is now being tipped by many to guide Sunderland to survival, including by former Sunderland goalkeeper Thomas Sorensen.
The Dane played at Sunderland for five years after arriving from Odense Boldklub in his homeland.
Now at Australian side Melbourne City the 39-year-old told FourFourTwo this week:
"I definitely think they can.
"Allardyce is a proven manager at that level. He is good at what he does. He is obviously looking for results because that is what they need. They need stability. They have gone through some tough times, a lot of managers and a lot of players coming and going.
"The league is so tight, but when you look at their squad I think they have enough to string some results together."

Allardyce has of course been in plenty of relegation scraps before. He kept Bolton Wanderers up for many season before eventually building a team that qualified for the Europa League.
He also helped West Ham to survival and is known to do whatever it takes to keep a team in the Premier League.
Sunderland may be 19th, but you will still find most folk predicting a typical Allardyce survival from the Wearsiders.
