"No draw is a bad draw until after the game is gone because we are capable of beating anybody, but you don't really get tougher than this one," he told the Express & Echo.
"It would have been good to have a home draw against a lower league team, but that is the way it is. We have to deal with it.
"It has been particularly sore subject this past few years, us not winning any of these FA Cup first-round ties. I was hoping to win a couple of games at least this season, but it is going to be difficult."
