"It's a fantastic win," Holloway told reporters following the game. "We had certain things to concentrate on and we did. I'm proud of the players.
"There's no point looking at the league table now, it's all about what it shows after the next three games. I was actually disappointed not to win the second half. We had the chances to put the game to bed."
Millwall return to action on Monday when they take on fellow strugglers Doncaster Rovers.
