The Swedish striker has impressed playing for Cityâ€™s reserves and Swedenâ€™s underage teams and did well on loan at Brommapojkarna, the club who developed him as a schoolboy.
"Iâ€™ll be grateful and take that comparison, but maybe itâ€™s a bit exaggerated," he told Eurosport. "I donâ€™t want to be the Swedish Rooney, and anyway I would rather be compared to (Sweden striker Zlatan) Ibrahimovic.
"Iâ€™m John Guidetti, I donâ€™t want to be anyone else. I just want to be myself."
Fellow Swede Sven-Goran Eriksson signed Guidetti for Manchester City in 2008 and the new Leicester boss has been linked with a swoop for him.
"I can imagine that (Eriksson) is interested, after all he was the one who got me to City in 2008," he added.
"But everything is up to City, and if they want to let me go or not.
"It would be a damned good loan for me, theyâ€™re a good team with great players. It would be awesome."
Guidetti has scored 14 goals in 14 matches for Cityâ€™s youth team and hit a hat-trick on his reserve-team debut against Burnley last season.
He feels he can succeed in any division - but asked to be handed a chance to impress.
"It doesn't matter if it's the Premier League, Serie A, the Championship or La Liga, I'm waiting for my chance, I feel that I'm ready to take the next step now," he added. "If somebody gives me the chance I will succeed.
"I carry on scoring goals and then we will see if I will go to Italy, get a chance at City or join Eriksson at Leicester. If I play well clubs will be interested.
"I havenâ€™t spoken to Eriksson as such - he is a manager and he has a lot to do all the time.
"You do your talking on the pitch by scoring goals and giving assists, you donâ€™t have to talk on the phone. So I guess we have talked a fair amount!"
