Neil Harris expressed his delight over Millwall's performance in their 1-0 Sky Bet Championship win at The Den against Leeds United on Saturday afternoon.
The Lions dominated the League leaders from start to finish and got their just reward on 73 minutes when Aiden O'Brien struck past Felix Wiedwald for his second goal of the season.
Harris credited his side for executing the gameplan to perfection against The Whites.
"We've played a lot of games this season where we've been as good as that, but not got the points," he said. "So it's very pleasing to play that well and win the game.
"We knew it was going to be tough. Leeds are top of the League and have scored the most goals and conceded the least. We worked very hard on Thursday and Friday to make sure the team had the gameplan right - credit goes to the players for executing it.
"We out-fought and out-run Leeds and won every first and second ball."
Despite the narrow scoreline, The Lions won comfortably and should have been victorious by a greater margain - something that the manager echoed.
"We could have had more. Steve Morison could be walking off with the matchball and George Saville should have done better with his chance. But, I'm pleased that we kept going.
"We came in at half-time and the players knew that they were excellent. I deliver the message, but sometimes the players deliver their own. They came in with the bit between their teeth that they weren't going to settle for a good performance and a point or coming off unlucky losers. They wanted it and that showed today."
