The Sky Blues, who started the season on minus ten after administration, have already got more points on the board than at the same stage last season thanks to Pressley's side's high-energy, attacking football.
Pressley said: "With the exception of the opening ten minutes, I thought we coped with the challenge brilliantly.
"We had a couple of scares early on from set plays and Joe Murphy, who deserves a special mention because he had been struggling with a virus, made a couple of outstanding stops.
"After that, it was relentless pressure from us. They couldn't get out and we had good shape but we had to show patience.
"I said to the group at half time that we had to keep passing with patience and not get excited about the game.
"Overall, I am absolutely delighted with the result and this was an example that we are victim of our own performances because Gillingham came here and gave us respect and made life difficult.
"These types of games can take until the last few minutes to win but, in terms of chances created, we had so many in the match."
