Guidetti is keen to kickstart his career with a move away in January.
He scored twice on his comeback from injury for Sweden's U-21s on Tuesday.
The 21-year-old, who has not played for City since September 2010, managed just over an hour in his side's 5-0 win over Malta in a qualifier for the European Under-21 Championships.
Guidetti has suffered an injury and illness nightmare over the past year and a half but is finally returning to full fitness.
