On-fire Aussie midfielder Jackson Irvine scored in his third straight league game after heading home the winner for Burton Albion overnight.
Irvine struck on 12 minutes to seal a 1-0 victory for The Brewers in their first clash with Derby County.
The Aussie also provided some sweet revenge for his gaffer Nigel Clough who was sacked by the Rams in 2013.
Clough said post-match: “It is another step in the fantastic story of this club over the last 15 or 20 years.
“We never dreamed we would even be in the same division as Derby, never mind beating them.
“But it’s not just about winning these games, it’s about staying in this division, and this is another three points towards that.”
Irvine, who made the switch to the Championship from Ross County in the off-season, has continued his blistering start to the season.
Last week he scored with a diving header in a 2-2 draw with Blackburn Rovers and hit the back of the net in a 3-1 victory over Sheffield.
Burton Albion currently sit in sixth spot on the Championship table after five games.
