The Lions are now just one point away from the top six, and their head coach is full of confidence about their prospects during the season run-in.
"It's 13 league games unbeaten since New Year's Day, but we've still got seven more to go," Harris told reporters in his post-match press conference.
"What we've achieved so far has been miraculous, but I want more - I've told them that.
"The players and the dressing room's driving it. You can see the spirit; the players laughing and joking during the game, and that's fine in top teams as long as they do both sides of the game. The playoffs are a reality."
