The Bulls boss was delighted to return to winning ways after a weekend defeat, as his side pushed aside Eccleshill United at the Forest Town Arena.
Ross Duggan was at the centre of it all again, scoring yet another first-half double in the space of 16 minutes to secure all three points with AFC seeing the result out professionally.
"Three or four had picked up little knocks and niggles so we had to change the back three, and personnel-wise we brought Anton in, so we didn't really know what to expect," the gaffer told Bulls TV after the game.
"We had an Eccleshill side that were physical and liked to play one way so we had to change our game massively to try and counter that.
"I'm absolutely buzzing from today - the bounce back has been great."
Chatfield admitted that going in at the break two goals up is not his ideal position, but was pleased with how his side killed off the game and saw the result out in such a professional manner.
"I hate two-nil at half-time - I'd rather be one or three-nil up, but to be fair to the lads they dug in deep.
"The second half wasn't pretty but we defended really well and we could have scored one or two more."
Even more pleasing for an "ecstatic" manager was the performance of players entering the starting XI: "Like I said, I didn't know what to expect - I knew that we could compete and many would have tried to change the system but we stuck with our roots and it paid off today."
Debutant midfielder Connor McMillan enjoyed a brilliant first display in a red shirt, beating the offside trap superbly to then whip in the ideal cross for Duggan to tap home for AFC's first goal.
"It was brilliant," he told Bulls TV, "to say that I've got a debut and an assist as well, it's been good and I've really enjoyed it."
The young winger hopes that his impressive debut could catapult him into more first-team action: "I think I've shown what I can do, and now it's up to the gaffer to pick me."
