Manager Mark Stimson could not hide his disappointment after seeing his Barnet side beaten 4-1 by Rotherham.
Kevin Ellison opened the scoring in the 69th minute for the Millers before substitute Tom Pope and Danny Harrison wrapped up the points.
Mark Byrne netted a consolation for the Bees in the 81st minute but prolific striker Le Fondre put the icing on the cake late on.
"Obviously we're very disappointed. So early after a game you have to be careful what you say because up until 65 minutes there was only one team in the game and one team who was going to win the game," said Stimson.
"Again we created some fantastic opportunities. Decisions in front of the goal might not have been the best and also an outstanding save by their goalkeeper and also hitting the crossbar.
"Saying all that we have and we just have to try and move on from here. Obviously the players are very upset like myself, because we don't like to lose at home, especially by that result. A bit similar to last weekend, created chances but didn't take them and you can see at the level you have to take them."
