Last weekend Sousa's old club ended a run of five league matches without a victory - beating Wigan 2-1 at the Liberty Stadium.
"Swansea started well, they had a difficult moment and then came an important win against another team that will be fighting to stay in the Premier League.
"I think they will stay up - it could be more difficult than last season but I feel the footballing philosophy [at the club] is strong enough to ensure survival."
Sousa was in charge at the Liberty Stadium for thirteen months before leaving to take over at Leicester City - a post he was sacked from after only eleven weeks. The Portuguese - along with Roberto Martinez - is credited with transforming Swansea from a side in England's lower leagues that played a fast 4-4-2 style of football to a possession-based, patience game that eventually secured promotion to a club league many consider to be the strongest in the world.
"I have said this before - Swansea are a unique club. Huw Jenkins [the owner] made a great decision several years ago to take on a new footballing identity and he wants to protect it because he knows that good football means good results.
"As a player Michael Laudrup delivered so much to football fans and it is great that he is manager. It is fantastic to see him on the bench at the Liberty Stadium delivering his knowledge and ideas to other players."
Swansea's next Premier League match is against champions Manchester City:
"As a coach I would love to have the best players - like City and Roberto Mancini have. It makes our job easier because they understand what managers demand a lot quicker.
"So far - for me - Chelsea look the strongest candidate to win the Premier League - they have good rhythm at the moment and quality in their squad.
