Graham Turner admits he hasn't seen much of Accrington but thinks they could slip up shortly.
"I've not seen an awful lot of Accrington. When we went up there I thought we played well and were unfortunate to lose the game 2-1," Turner told BBC Hereford and Worcester.
"I didn't think they were as good as their lead in the table would suggest.
"There might be a time over the next month or so when they start to come unstuck. It usually happens, somebody has a sticky spell during the course of the season.
"It could happen to Accrington fairly shortly.
"If that is the case we've got to keep plugging away and hope to be up there."
Turner also admitted Hereford United had been disappointed with the first half of the season but revealed the stats were good.
"Yes the statistics tell us that we have, compared with the same date last season, got two more points now having played two fewer games. And that's after a disappointing first half to the season.
"So it's not too bad after all!"
