Dean Smith revealed that he warned the Brentford squad they would be in training next weekend if they didn't step up their performance at Burton.
The Bees found themselves 3-1 down at half time at the Pirelli Stadium after a Marvin Sordell brace and Cauley Woodrow free kick cancelled out Sergi Canos' opener.
Lasse Vibe pulled a goal back before the Spaniard equalised just after the hour mark.
The Bees had chances to go ahead but only did with five minutes to go through Vibe and, moments later, wrapped up the points as Jota drove the ball home from the Dane's cross.
And Smith revealed that the dressing room chat at the break was calm, but did include the threat that the squad would be in next weekend.
“There was a threat at half time that we'd have them in all weekend next weekend so they'll do anything to have a weekend off,” Smith said.
“The coaching staff had a chat outside the dressing room and looked at the goals – there were clear heads from myself, Richard (O'Kelly), Thomas (Frank) and Roycey.
“We didn't think we'd played that badly. We had to remind ourselves they scored three set pieces. It was a sloppy free kick on the edge of the box from Romaine and Dan will be disappointed he got beat on his side from the free kick.
“It was the way we marked from the throw ins that led to the corner. They felt the sharp side of my tongue about the goals we conceded.
“The easiest thing to do would have been to change the team but I still felt we were in control of the football and I felt we had to be more patient and have a bit more pace.”
Smith also told the squad that they are worthy of being a top half team but they have to prove it on the pitch.
He explained: “I said that I believe we're a top half team and we've got to prove it to people. We took a deserved lead and then conceded three really poor goals.
“I never believed it was game over because Lasse had got behind them all game. Sergi looked a threat and Jota looked a threat.
“I knew today I had some impact players who could change the game and up the tempo when we needed it.”
