TourÃƒÂ©, 27, spent three trophy-laden seasons at Camp Nou before joining City last summer for Ã‚Â£24m.
And the Ivory Coast international is confident that continued investment from CityÃ¢â‚¬â„¢s billionaire owner Sheikh Mansour bin Zayed Al Nahyan will see his new club emulate the success of the Catalan giants.
“You cannot compare Barcelona with City right now because Barca are at the top and have top-quality players,” TourÃƒÂ© told the Sun.
“They have Leo Messi, Xavi, AndrÃƒÂ©s Iniesta and Dani Alves, who are fantastic. But we are still signing new players.
“In a couple of years we could be better than Barcelona. What we need to do is continue to work hard and improve with every game.
“I keep saying to my brother Kolo and my family that City have great players but we need to continue to work hard to become great.”
Roberto ManciniÃ¢â‚¬â„¢s men currently lie in third place in the Premier League table, eight points behind leaders Manchester United having played a game more.
And TourÃƒÂ© says City must focus on securing Champions League football next season. He added: “Our target is still to be in the Champions League next year – that is very important for this club.
Ã¢â‚¬Å“But it will be tough to stay in there because Liverpool are coming and I’m sure Chelsea will be back.”
