The 20-year old Swedish striker has attracted plenty of attention since scoring 20 goals in 23 appearances whilst on loan with Dutch club Feyenoord last season.
Guidetti's representative Roberto De Fanti has indicated that a move to Italy could be on the cards with the player not interested in sitting on the bench at City.
"I have also spoken with Roma in the past, but they have many strikers and I don't see a real possibility with them.
"Playing in Italy would be a dream for him, considering his origins. I know (Lazio sporting director Igli) Tare well and tomorrow there could be a new meeting with him in Milan.
"John is a classic striker, he looks like (Gianluca) Vialli for features.
"At City he would have difficulty in finding space, given that there are many forwards there. He follows Serie A and he would love to play there."
