Barnet, three points adrift at the foot of League Two, are keen on a striker who has quickly fallen out of favour at the ABAX Stadium following his summer move from Dover Athletic.
Three other League Two clubs are keen on Miller who prefers a move to the south. Posh are demanding a fee for Miller.
Posh have turned down bids for improving winger Dannny Lloyd, according to chairman Darragh MacAnthony’s Twitter feed.
MacAnthony also revealed Posh are in talks with three potential new players. Posh manager Grant McCann hinted after Saturday’s (January 13) creditable draw at League One leaders Wigan that a couple of new players might arrive before this Saturday’s (Janujary 20) home match with Oldham.
Posh have rearranged their League One game at Bury for Tuesday, March 13. The match was scheduled for Saturday, January 27, but Posh are now in FA Cup action that day.
Posh will host Premier League Leicester City or League One rivals Fleetwood Town in a fourth round tie. That third round replay takes place tomorrow (January 16).
