Former Chelsea midfielder Frank Lampard will turn out for City in the coming season having signed on loan from New York City - a Major League Soccer franchise owned by the same powers as those in charge of the Barclays Premier League champions.
After falling foul of UEFA's Financial Fair-Play regulations, City have been restricted to a 21-man Champions League squad this year, with eight home-grown players required in their Premier League squad.
Former Barcelona and Spain striker David Villa has also signed up to play for New York City next season - but has instead moved on loan to another club owned by the same group - Melbourne City of Australia's A-League.
Although his move has not been officially confirmed, City manager Manuel Pellegrini has announced that Lampard will now occupy one of those berths after the England midfielder sealed a shock return to the Premier League just months after leaving Chelsea, who had not offered the 36-year-old a new deal at Stamford Bridge.
But Wenger, who has always been a staunch advocate of financial fair-play, believes the move could benefit City at the expense of Arsenal and their fellow title rivals.
"It is a surprise," he said when asked about Lampard's loan move.
"After the statements we hear it is a surprise but it looks like all of these 'City' clubs will feed the main club Man City
I heard they want to buy five clubs all over the world.
"I don't know the rules well enough but they brought a franchise for 100million US dollars (£59.4million) to play in the States next season.
"At the moment the players they sign cannot play until next year so they will register them in the clubs where they put them and they can get out on loan.
"Is it a way to get around the fair-play? I don't know
We are happy to dedicate the money to just run our club
There is not a lot of surplus to run other clubs."
Wenger was talking following his side's 1-0 Emirates Cup defeat to Monaco, a result which saw Valencia walk away with the pre-season trophy.
Former Chelsea defender Ricardo Carvalho played in the game and admitted he would rather see Lampard still turning out for the Blues.
"I'm a supporter of Chelsea, I like Chelsea and they are strong," he said.
"Of course I would prefer to see him in a Chelsea shirt rather than a Manchester City shirt but you have to respect his decision.
"He's a great friend of mine and a great person as well
I will wait and see how he does but like I said, I'd prefer to see him back in a Chelsea shirt rather than a Manchester City shirt."
