It was a first win in eight for Argyle and came just as the game looked to be petering out into a 0-0 draw.
He said: "We knew we were in for a battle and we defended well as a team, I thought we created one or two problems ourselves, too, though they had chances.
"We worked hard, though we didn't play well. But we ended up with a scrappy 1-0 win and sometimes they are the best results.
"I want us to believe in ourselves a bit more and pass the ball. We went into a scrap and I was pleased with the way the lads dealt with it.
"We have not had the breaks this season, but everyone was in the right place at the right time for the goal. We are not getting carried away but I know sometimes a win like that gives you the kickstart you need to get back on a run."
