The England international moved to the Etihad in a deal worth £49 million and received criticism from a number of Liverpool fans for rejecting a £100,000-a-week deal, and showing a perceived lack of respect for the Reds.
However, the Arsenal boss has defended the 20-year-old, claiming he did nothing wrong during his time at Anfield, describing him as a 'special' player.

As relayed by FourFourTwo, Wenger said: "I personally rate Raheem Sterling, we will see that in the longer term, I personally don't think that Sterling was making a lot of drama. It's just during the transfer window that that happened.
"During the season the boy was quiet, never made any stupid statement. I don't think he made too much noise. Will they miss him? He's a quality player. But they bought [Roberto] Firmino. We will see what he will produce. He is a similar player.
"But let's remember two years ago with [Luis] Suarez, [Daniel] Sturridge and Sterling, they scored over a hundred goals. You need special quality to do that, and Sterling was part of that."
Sterling has been prominent in Manchester City's blistering start to the new campaign, providing an assist for Alexander Kolarov in the 2-0 win over Everton yesterday.
Liverpool are sure to miss the England international who became a star at Anfield after breaking into the first-team. However, on the basis of the opening two games, Brendan Rodgers has spent well on replacements for Sterling.
Christian Benteke has hit the ground running, opening his account against Bournemouth and proving to be a constant menace for opposition defences.
The Reds face their toughest test so far, heading to a ground where they were hammered 4-1 last season, but have shown a more resolute side to their defensive game so far this season.
VITAL GAME FOR ARSENAL
Arsenal were impressive in their win at Crystal Palace, bouncing back from the opening day defeat to West Ham and Wenger will be keen to avoid any more slip ups so early in the season.
Wenger is coming under pressure from sections of Arsenal's fan base for failing to sign players in the transfer market and another home defeat would intensify the pressure on the French boss to make additions.
The Gunners boast an impressive record at home against the Merseyside club, losing one of their last 18 fixtures and will be looking to get their first home win of the season and keep the impressive run going.
