Reports claim the Premier League club will look to make a summer move for defender Willems with Guidetti going to Holland.
Guidetti was signed by City as a 16-year-old in April 2008 and has yet to make a senior appearance for the Premier League champions, having been severely affected by a virus suffered towards the end of last season.
However, now recovered and playing with the club's development squad, he is highly regarded and scored 20 goals in 23 games while on loan at Feyenoord last season, and he has already played for Sweden in a friendly against Croatia.
However he has no intention of moving to PSV and told Sportwereld AD: "I will never, ever play for PSV."
He added: "In the Netherlands, Feyenoord are the only club I would want to play for.
"Everyone knows that."
