The Argentine has proven to be a consistent goalscorer in England's second tier, firstly with Watford and then more recently with Sheffield Wednesday, meaning that Derby are keen to snatch the striker of Championship rivals Wednesday.
Forestieri scored 15 goals in the Championship last season for the Owls, who narrowly missed out on promotion after a Play-off final defeat to Hull.
Derby appear to want to add to their attacking options, but it remains to be seen whether Wednesday would be prepared to listen to offers from a fellow Championship promotion rival.
