The Swedish striker has been with City since 2008 but has had to wait patiently to make his breakthrough at the Etihad Stadium and has been continually loaned out.
Having had spells with IF Brommapojkarna, Burnley and Feyenoord, the 21-year-old now has an opportunity to prove to Man City that he has the talent to shine in the English top flight after linking up with Stoke on a deal until the end of the season.
He hopes a good few months at the Britannia Stadium will stand him in good stead to finally make an impression back at Man City, but his main aim is to help the Potters.
"I hope I can prove myself," said Guidetti in The Sun, after making his Stoke debut as a substitute in Saturday's 1-0 defeat by Crystal Palace.
"I know Man City believe in me. If I can score as many goals as I can until the end of the season, you never know.
"It is most important we get Stoke up the table and start winning as a team."
