Salisbury manager Steve Claridge spoke to their OS after Saturday's 1-0 defeat at Hereford.
"It was a very quiet dressing room afterwards. We are not used to losing and not accustomed to dealing with it. People were a lot more disappointed than they should have been.
"But I said, 'Hold on - we've got another 90 minutes to go and win this.' I will be getting across to them again at training tomorrow night that we've got another opportunity and a massive one at that, being just a goal down.
"We didn't play as well as we can, we know that. There were four or five who weren't where we need them to be and didn't do themselves justice.
"I think one or two took a step back away from home. That won't be happening again. At home we will take a step forward. There is so much more to come.
"If we are going out - and I don't think we are - we are going out having a right go. We will ask far more questions of them in the home leg. It will be higher tempo and we will test them a lot more. Come hell or high water, we won't be leaving anything out there."
Claridge called for more backing for his side next Saturday when the second leg takes place at Salisbury.
"I want to see all our tickets sold this week," he said. "You saw the atmosphere at Hereford and what it meant to their support. They were passionate to say the least. We want that now.
"Our fans need to give us the backing. The boys said how fantastic the support from our fans was up at Hereford. Now we need to ramp that up four times over and sell our 2,500 tickets.
"How many times is being 90 minutes away from Wembley going to happen in Salisbury's history after all?"
