And after ending the day a point clear at the top of the table, O's boss Slade claimed his side were going about their business in the right manner both on and off the pitch.
"We probably could have had a couple more than the four we scored but we continued to create chances all afternoon," said Slade, who has been linked with the vacant managerial post at Sheffield United.
"It is never easy for a team when they go down to 10 men and they are chasing the game but we were solid.
"It was nice to get a clean sheet, especially away from home because when you are top of the league teams do want to beat you.
"Every game is going to be a challenge but the fans are right behind us and we are playing some really attractive football.
"There is belief in the camp but there isn't any arrogance about us and we will continue trying to do the right things.
"We have the right to be confident and we were ruthless in front of goal.
"It is important that when you have your foot on the throat of the opposition that you don't take it off.
"The players are enjoying their football and we looked very dangerous."
