The 0-0 drab draw at The Den rivalled Saturday's 1-0 defeat against Leyton Orient for the title of the poorest showing by the team for some time as Jackett's men once again struggled to get out of first gear, with the fans showing their displeasure by booing the team off at full-time.
"We had the bulk of the ball, but we did not do enough," moaned the under-fire boss after the game. "I was very frustrated with our efforts going forward.
"I thought their keeper made a very good save late on, but we really lacked a spark. We are lacking confidence at the moment - confidence is earned and we have to work at that. Nobody gives you anything in this game and the players have to learn that.
"A clean sheet is something to build on, but my over-riding emotion is one of frustration."
