Petrovic should have been making the move to Dutch club Vitesse Arnhem but the deal fell through at the 11th hour.
Now Partizan have revealed that Petrovic is close to a move and reports in Serbia suggest the club in question is Blackburn.
The 22-year-old Serbian international has been with Partizan for three-years last season he was one of Super Liga’s top scorers last season and his goals helped his club to the title.
"We have a serious bid for Petrovic and the chances are that there will be a transfer," said the club's sporting director Mladen Krstajic.
