Guglielmone has insisted that Cavani opted to stay with PSG after the French club assured him that he would be their number one striker during the upcoming season.
The Uruguay international had been heavily linked with United as they are on the lookout for a world class striker after allowing Robin van Persie to join Fenerbahce and opting against giving Radamel Falcao a permanent deal after a poor lone spell at the club last season.
"This summer Edi has received interest from top clubs who are chasing a centre-forward," Guglielmone told Journal de Dimanche. "He hasn't listened to them because he was given guarantees about his position at the end of last season.
"We have been led to believe that Ibrahimovic will pay further and further away from the box in order to touch the ball more, leaving the striker position for Edi to fill, which was the case several times at the end of 2014-15. In such conditions, Edi will be happy at PSG."
Cavani, who scored 31 goals in all competitions last season, joined PSG for €64.5 million from Napoli in 2013.
