The Swedish striker has been a revelation since moving to Celtic on loan.
Aged just 19, Guidetti sparkled for Feyenoord in a season long loan spell in 2011-12, registering 20 goals in 23 games for the Rotterdam giants and announcing himself as a player with the ability to score goals in a competitive league.
Fast forward a few years, and further loan spells to English clubs didn't really get off the ground, meaning that when he returned to the Etihad he was often further away from the first team than when he left.
Still only 22-years-old, the Swede is now proving his quality in another league, after joining Celtic for the rest of the season, and got up to 8 goals in 8 games with his treble over Partick Thistle in the Scottish League Cup this week.
Of course, Celtic have some form when it comes to Swedes starring at the club, given Henrik Larsson's association with the Hoops. The ex Barcelona man registering an astonishing 241 goals in 313 games at the club, and was one of Celtic's greatest modern day players.
Guidetti has some way to go before being talked about in the same breath as Larsson, but his first few games in Glasgow seem to indicate that he is already one of the best strikers in Scotland.
Looking at the strikers Manuel Pellegrini currently has on offer at Manchester City, there is at best room for another forward to come in to bump the first team options up to four.
However, the problem attacking options is worse than that, with Edin Dzeko and Stevan Jovetic both struggling to seize opportunities for the Premier League champions, and while Sergio Aguero continually proves himself the one absolutely top class attacker at the club.
The ease with which Guidetti started scoring goals at Celtic would serve him well if he was to be given a chance back in Manchester, and if he can carry the same goalscoring form back south of the border, he could end up being a valuable player for Pellegrini.
