Burton came under fire despite a seventh successive home win keeping them among the promotion frontrunners.
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 "lackadaisical" 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 lackadaisical 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."
But Summerfield was only too happy to heap praise on winger Jacques Maghoma after another superb display.
Maghoma, who scored twice in the win at Fleetwood, laid on close-range finishes for Michael Symes and defender Marcus Holness in the 11th and 27th minutes and then took his tally for the season to 13 with a superb volley into the top corner from the edge of the area seven minutes later.
Summerfield said: "Jacques is a player we want to get on the ball as much as we can because he can be so influential. He was the turning point in the game for us at Fleetwood and here he did great to set up two goals and score another. He is a real quality player."
Substitute Guillem Bauza had reduced the deficit for the Grecians with a crisp shot from the edge of the area in the 70th minute and the visitors struck again four minutes later when a Scot Bennett header was adjudged to have crossed the line. It proved too little too late, though Paul Tisdale refused to criticise his team.
He said: "Burton deserved to win, simple as that. We did our best, but it wasn't good enough because on the day they were better than we were. I'm not too unhappy with my players because sometimes you have to accept there are days when the opposition are better than you.
"We didn't read the game quite as well as we should have done and I've highlighted a couple of areas where we need to improve, but I'm not going to criticise players who haven't let me down at all this season."
