The Morocco international became Mark Hughes' seventh signing of the summer late last night after the Potters were able to agree a deal with Premier League rivals Liverpool.
Assaidi, who impressed during an identical spell at the Britannia Stadium last season, told Stoke City Player, "I'm very happy to play again for Stoke.
"It's like I'm back home because I know everyone.
"I know the players, I know the boss and I know the fans of course.
"I like the fans, they still like me I think and I'm very happy to be here.
"Everyone here has always been really nice to me, they treat me well and that's why I'm happy we finished this deal."
Assaidi netted five times in 25 league and cup appearances for the Potters last term, the last of which coming in the penultimate game of the campaign against Fulham.
He scored in the 4-1 triumph at the Britannia Stadium but also suffered a re-occurrence of a knee injury that ruled him out of the season finale at West Bromwich Albion.
The 26-year-old has been busy recovering from the setback over the close-season and cut short his holidays in order to give himself more time to bounce back.
"I've worked very hard and I've not had a long holiday over the summer," he revealed.
"With my injury I've had to train really hard with Liverpool; in the gym as well as out on the training pitch so I can't wait to play my first game.
"I've had a little bit of pain with my injury but now I am fit and hope to play."
The decision of when to reintroduce Oussama Assaidi into the fold is an unenviable task for Mark Hughes after he saw the Potters claim a fantastic 1-0 win at the Etihad Stadium last weekend.
The Club's first away victory over the Champions since 1997 was dampened by Peter Odemwingie's second half injury, however, and Assaidi will be competing for a place in the side with the likes of Bojan, Marko Arnautovic and Jonathan Walters.
"They played really well against Manchester City, who aren't a bad team at all!" he smiled.
"The competition for places here is good and that can only be good for the team.
"I know what my qualities are though and I need to show them.
"If you play and train well then the boss will let you play - the decision is up to him."
