Guendouzi has started all four Premier League games so far this season and impressed many.
Aliadiere knew Guendouzi would become a top player and recommended Arsenal to him for his progression.
"I knew when I first saw him that he had something special and that a lot of clubs would be after him," Aliadiere told Goal.
"I said to him that for his development Arsenal would definitely be the right place for him.
"You can go to big clubs and never get a chance but Arsenal always give a chance to their young players.
“I thought it'd be good for him."
Aliadiere though is surprised at how many games Guendouzi has already played in his early days at Arsenal.
"To be honest yes I have been surprised [that Guendouzi has started so many games]," he added.
"When I saw him joining the club I didn't expect him to start straight away, I thought it would take him a bit of time to adapt but he's such a confident lad.
“When I was playing with him at Lorient you could see that, on top of having the talent, he's just so confident in himself.
"It doesn't matter who you are, what career you've had, he's happy to be whatever and friends with everybody.
"He's just a nice and happy guy to be around.
“I'm not surprised he's getting on with everyone in the dressing room."
