Manager Kenny Jackett hailed Millwall's display as his side extended their unbeaten run in the npower Championship to six games after mauling Huddersfield 4-0.
Striker Chris Wood took his Lions tally to five goals since arriving on loan in September with a brace either side of the break, while James Henry and Liam Trotter added goals after 78 and 87 minutes respectively.
Huddersfield's disastrous trip to London was made worse late on as Jack Hunt received a straight red card.
"The result pleases me a lot. It was a tight game for quite a long time and I couldn't necessarily see the 4-0 coming," said Jackett.
"The second goal was a very good goal from our point of view after we'd been under a bit of pressure and I think that's what killed the game off. I couldn't see us losing once we'd got that second."
Huddersfield first team coach Glynn Snodin said: "It was the last 25-30 minutes that killed us - we lost a bit of our discipline.
"In the first half it was fairly even and I think we felt a bit unlucky to be a goal down at half-time.
"But some of the players lost their discipline and we were pushed. They're upset but we've talked to them about it in the dressing room and we'll try to make sure it doesn't happen again.
"Jack was sent off for dissent. He felt he'd been fouled and the referee has sent him off for what he has said. In fairness, he's apologised to the rest of the players and put his hand up to that one. I think it's in the heat of the moment - we've all done it - but he recognises he's made a mistake.
"We've got a good team here but the last two away games have been disappointing. We've got a bit frustrated today because we were creating chances but nothing was quite dropping for us."
