McGoldrick has scored or assisted five goals in six starts since signing for Sheffield United, with all but one of those contributions arriving in the Blades' last two outings.
Blackburn, though, should not need telling about McGoldrick's capabilities, having shown interest in the striker at the start of the summer window, according to the Sun.
They were one of there clubs - alongside Bolton Wanderers and Queens Park Rangers - reportedly ready to offer deals to the Republic of Ireland international, whose contract with Ipswich Town had recently come to and end.
McGoldrick, however, remained a free agent until Sheffield United came calling two months later, offering him a trial spell initially, then a one-year deal after he impressed the Blades manager Chris Wilder.
And having already made one of those allegedly interested clubs pay for their apparent reluctance - scoring the winner against QPR in August - McGoldrick may be on a point-proving mission once again at Blackburn.
