The Brewers survived a late fightback by away-day experts Exeter to record a 4-2 win that lifted them into third place in the League Two table.
But it was not all praise for Gary Rowett's men as assistant boss Kevin Summerfield accused them of a "lacksadaisical" approach.
The Burton number two said: "I think there was a danger we might get carried away after the 4-0 win at Fleetwood.
"I think it showed because we were a little bit lacksadaisical and, despite being three up at half-time, Gary and I weren't that happy.
"We did manage to raise the tempo a little bit in the second half, but over the 90 minutes I don't think we were as good as we have been over the last three or four weeks."
