The Daily Star reports that the three clubs all sent scouts to Fiorentina’s 3-2 weekend win against Udinese.
Jovetic has a buy-out clause of £40million, but Fiorentina are ready to sell him for less.
The Montenegro hitman’s current contract at Fiorentina is set to expire in the summer of 2016.
Jovetic said: “I am content in Italy but I’m always looking out to improve myself. I have been looking out for a chance to play in the Premier League and I am prepared for that challenge.”
