Guidetti's father confirmed the decision this week.
"Yes, in the form of exclusive representation, it is over. But then, various forms of collaborations can always happen in the future," Mike Guidetti told fotbollskanalen.se.
For now, as Guidetti does not have an agent, it is Manchester City who will represent him.
Mike adds: "It is the club that holds the primary responsibility for John. Since he is with City and does not intend to leave the club, there is no problem. John's not between clubs in any way."
