The Swedish striker remains highly regarded at the Etihad Stadium, but has been left frustrated in his efforts to earn senior recognition.
He was initially sent out on loan by City to gain valuable experience, and impressed while scoring 20 goals for Feyenoord in 2011/12.
It was expected that a spell in Holland would open doors for him in England, but Guidetti has since spent 18 months on the sidelines.
Knee surgery over the summer has prevented him from staking a claim under Manuel Pellegrini, and speculation is now suggesting that he will be on the move when the transfer window re-opens.
Various clubs from across Europe are said to be keen on the talented 21-year-old, and he is ruling nothing out at this stage.
Guidetti told TV4: "I want to play football. Whether that is at Manchester City or somewhere else, I don't know.
"Right now, it's a matter of training and fighting. Then, in January and onwards, it's time to show."
