The manager was relieved to avoid extra time and potentially a replay, as well as keep yet another clean sheet, as his side edged past Graham Street Prims to reach the Buildbase FA Vase Second Qualifying Round.
A game dictated by two outstanding performances from two determined goalkeepers was decided by a 93rd-minute winner from Ross Duggan, who celebrated his 12th goal of the season in style.
"It was 90 minutes of end-to-end football," Matt Chatfield told Bulls TV after the game, "it wasn't the prettiest and if I was a fan I'd be disappointed to have watched that game.
"But cup games aren't always pretty and I think we were unlucky not to score in the 90-odd minute last week against Heanor - we've done it today with a bit of brilliance.
"The main thing is we're into the next round of the cup."
The gaffer admitted plans were already in place for another 30 gruelling minutes of play, but was relieved that Duggan found the late winner: "We always have to plan ahead, we have to plan the what-ifs, and luckily we didn't have to use it today which is great."
Saturday proved to be far from the greatest advert for non-league football, but what pleased the Bulls manager more than anything was a fifth clean sheet from their first six outings - a feat which Chatfield said feels like "scoring another goal".
"It's brilliant for us knowing that if we've only managed to score one, we've won the game because there's going to be a clean sheet up on our end - it's just what we want."
Two new signings made their debuts yesterday - defender Jack Hague who made his full debut, and young midfielder Ellis Wright who replaced Connor McMillan in the second half - and Chatfield was delighted with their contributions.
"We've got an injury crisis which gave Jack the opportunity to start; I think he did really well, kept his shirt, he's done very well - we only brought him off because he hasn't played 90 minutes for a long time.
"Ellis came on and did really well, impressed when he got on the ball... I would like to have seen a bit more defensively but you can't say much about a lad who doesn't know anybody in the side.
"It's two impacts that we wanted."
Man-of-the-Match Richard Williams had a hand in that crucial fifth clean sheet from six, and the defender had high praises for a determined Prims side.
"Every team that's below us always come to give it all they've got, and that's what I think they did today - there were no surprises," he told Bulls TV.
"We kind of underestimated how good they actually were.
"I think the overall performance tested our character today, we've got a lot of phenomenal players that I'm delighted to play with.
"It just showed how much we wanted to gel together and dig in and grind a result out regardless of the mistakes we were making, and I think that just shows the true calibre of the team we've got for this year."
