The Hoops are 19 points clear of Motherwell at the top of the Premier League and firmly on course to retain the title for the second year in a row.
But Lennon is refusing to take any success for granted, and told his players to focus on the games as they come.
"You can't be as blase as that," Lennon said. "What we have to do is keep winning and force other teams to keep winning.
"So we have to beat Dundee and then Motherwell and if we win that then that will increase the gap over them but it is all ifs, buts and maybes at the minute.
"The players are going for a championship so I don't think there is any extra motivation needed.
"There is clear daylight between us and the rest and we want to reinforce that lead, whether it be against Dundee or whoever."
And Lennon will not be underestimating Sunday's opponents Dundee, who sacked manager Barry Smith in midweek.
"Dundee have had their problems but we are fully focused on what we have to do which is win the game and win it well," Lennon added.
