The young Reds were in complete control by the break in the East Midlands, thanks to a first-half hat-trick by Gabriel.
Captain Amir Ibragimov added a fourth midway through the second half from the penalty spot.
Darren Fletcher’s side opened the scoring at the Moor Farm Training Centre in the fifth minute with a right-footed shot from Gabriel.
Our fast start continued as Ibragimov went close with an effort which was saved by Derby goalkeeper Cristiano Dzialuk.
Just a minute after hitting the crossbar from outside the box, Gabriel doubled our advantage in the 14th minute with another right-footed effort.
