The Gunners fans are yet to see much of their summer addition, who moved to the Emirates Stadium from Italian side Sampdoria.
"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.
Torreira has made substitute appearances in each of Arsenal's four Premier League games so far and is honing in on a first start after he made a decisive contribution in last weekend's 3-2 victory over Cardiff, providing the assist for Alexandre Lacazette's late victor.
"That's the thing I'm hanging onto to say "No this team will get better".
And though Aliadiere is unsurprised that the teenager has made a name for himself within the club, he has been shocked by just how well he has been able to raise his game with the eyes of the world watching him - something he puts down to the player's self-belief.
"To be honest yes I have been surprised [that Guendouzi has started so many games]", said Aliadiere. "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", Aliaidiere said.
"It doesn't matter who you are, what career you've had, he's happy to be whatever and friends with everybody. I'm not surprised he's getting on with everyone in the dressing room".
Goalkeeper David Seaman also weighed in on one of Arsenal's newcomers after the game, telling Bernd Leno to stay patient.
"But it goes back to time again, I'm still hopeful".
Cech's spot in the team has been increasingly questioned as Leno is more used to Emery's style of play, but Seaman said the Germany worldwide has to earn the right to play. He has to be patient.
