KENNY Jackett hailed the influence of Millwall's fans after they roared the Lions to a famous FA Cup win over Aston Villa at The Den.
John Marquis' dramatic late winner secured a place in the fifth round draw, which takes place on Sunday, and piled more pressure on Villa boss Paul Lambert.
Darren Bent had put the visitors in front midway through the first half, but Danny Shittu restored parity five minutes later before Marquis headed home in the 89th minute.
"It was an excellent win considering the injuries that we had," Jackett said. "To a degree, we had some players playing out of position and a slightly imbalanced team.
"It was a fantastic night. The crowd generated a great atmosphere and I'm very appreciative of the way they drove us on. The link between the players and the crowd was a big one.
"They drove each other on and I'm very pleased for both sets because all of our perseverance was rewarded.
"We persevered after going behind and did well to come back from an early goal. I thought Andreas Weimann's acceleration to go past Shittu was excellent and then Bent found the finish.
"We got a goal back from a set piece which we've been poor from this season, with the quality of our delivery from James Henry. We should score more goals from corners.
"Into the second-half, we put pressure on Villa and got the late goal. It was a terrific save to start with from Shay Given but John has followed up with the rebound."
