Ian Holloway revealed that a rare Millwall away win was inspired by a heavy defeat on the training ground this week.
The Lions boss made wholesale changes to the side he was intending to play at the City Ground against Nottingham Forest - after they were beaten heavily by the players who were not going to be involved, in a practice match.
Holloway said that had inspired him to make five or six changes to the side he was going to field - and the end result was just their third away win of the campaign.
Goals from Scott Malone and Lee Martin put Millwall in charge before half-time and, while Forest pulled one back through Jamie Paterson, Millwall boosted their hopes of avoiding the drop with a massive 2-1 win.
"It was a vital win, we just need more of the same in the remaining games now," said Holloway.
"I picked a different team this week but that team got beaten in training, by the ones I didn't pick. I wasn't very happy, so I made five or six changes to that team, to include some players who had confidence.
"Hopefully we can try and get a few more performances like that out of the team in the coming weeks."
Holloway was particularly impressed with the performance of Martin, who netted the second goal.
"Lee deserves a big mention, that was his first goal for a while and I thought he was superb," he said. "We have some good players, it is about getting them to gel and getting a few more goals.
"I am delighted for Scott Malone, whether there was a deflection on his shot or not. But goals came from us being calm. The crowd got behind them in the second half and we hardly got a decision out of the referee. But we got the win."
Forest caretaker boss Gary Brazil blasted his side's first-half display, which he said shocked him coming after a positive display at Ipswich last weekend. The result left them five points off the play-off places with six games to go.
"I did not see that first-half performance coming," he said. "The players have been in a positive frame of mind, following the display at Ipswich.
"But after 20 minutes you could see we looked nothing like that. We did not want to earn the right to play. We did not want to do the scruffy side of the game. We didn't win headers, we didn't win tackles, we did not stop them from playing the way they wanted to.
"The two goals were very disappointing from our point of view. We gave ourselves a real problem.
"We got a goal, through Jamie Paterson, in the second half and you wanted to push on for a win after that. But, as much as we huffed and puffed, overall we were disappointing. It is a surprise.
"We still have a lot to play for and a lot to fight for. But we have to start picking up points."
