The manager and seven of Hemel Hempstead’s squad moved to Vauxhall Road in the summer from the Essex club.
They have had incredible success so far - sitting second in the National League South table after an excellent first three months.
Saturday sees Moore make an emotional return to the club he took to their highest ever finish last season.
But he says he and the other players going back to the Aspect Arena can’t let the occasion get the better of them.
Moore told us: “I have still got friends at Concord - I keep in touch with a lot of people there. It’s a fantastic club.
“We had a really good season last year but it’s about the here and now and our focus has got to be purely on getting three points on the board on Saturday.
“We’re really happy with how things have gone. There’s a real togetherness in the group - we’re in a good place.”
Moore has told Hemel not to read anything into Concord’s form.
Rangers have lost their last five but that makes them an even more dangerous opponents according to the 32-year-old.
“It’s got to be just another game,” he said. “We’ve got to go there and be professional.
“Concord are a young, energetic side and they will give us a very good game, I’m sure of that. It’s going to be really difficult but we are up for the challenge.”
