"Our attitude was better this week and if we'd taken that chance, we probably would have gone on to win the game," said Coleman to the media after the game.
"I was pleased with our tempo early on in the game and I knew Plymouth would come here, get men behind the ball and look to hit us on the counter. My only criticism was our lack of imagination.
"If we'd have come in and got a 0-0 draw, you might say that is something we can build on. But the only way we are going to build up our confidence is by winning games."
