City added to this in the second half, with Nico O’Reilly, Barrington who grabbed his brace and a Jadel Katongo penalty.
Derby scored a fantastic free kick late on through Marko Borkovic as we put in a fine performance to edge us closer to be crowned champions.
With the knowledge that City could win the title next week, if we secure victories against both Derby and Newcastle, we made an electric start to the match.
Derby set their stall early in the match, but our sustained pressure from City's frontline managed to find a path to goal.
Borges was unfortunate not to grab his brace, after fast feet by Adam got him into space, and crossed it to the winger who’s deflected shot went to Roberts’ palms.
It was not long before we doubled our advantage, as Nico O’Reilly played a pinpoint through ball to Borges, and his squared ball met Dan Ogwuru for a poaches finish.
Soon after the restart, we found ourselves in an attacking position once again, as O’Reilly laid the ball off to Luca Barrington, who stuttered his shot before he found the top corner.
Less than a minute later, Adam, who was having a fine game, added his name onto the scoresheet, after great passing play on the right found Barrington, his cross found the number eight who was in the right place at the right time to poke in.
We nearly had a fifth before the half time whistle, as Borges picked out Adam perfectly, but he could only find the Derby keeper’s leg as we went into the break with a good advantage.
The visitors came out with renewed confidence for the second half, with their control on the ball disrupting our rhythm.
But we reacted well, as the Young Blues pounced on their first opportunity of the half, as O’Reilly placed the ball into the net, after a neat set up by Ogwuru.
We found our first half levels again after our fifth, as Barrington converted his brace minutes later, when the ball found him in the box, he passed it into the bottom corner.
Clear cut opportunities came few and far between, until we were awarded a spot kick by the referee, which Jadel Katongo slotted away calmly to put us seven ahead.
Derby reduced the deficit late on, as a Marko Borkovic freekick, was hit sweetly past George Murray-Jones to end the scoring.
