The Irish 20-year-old, a Rams fan, joined in with the banter between the two East Midlands rivals online and could not contain his delight as Steve McClaren's side demolished the City Ground outfit in today's early Championship kickoff.
Craig Bryson's three goals in today's game at the iPro Stadium meant that he became the first Derby player to score a hat-trick against Forest since Steve Bloomer did the same at the Baseball Ground in 1898.
