Crawley Town manager Steve Evans believes Torquay could offer a tougher test than previous Cup victims Swindon and Derby. The Reds, who face the Gulls on Saturday, are bidding to become only the sixth non-league side to make it into to the fifth round of the FA Cup.
Evans told BBC Sussex and BBC Surrey: "We want to be in the FA Cup fifth round and draw a monster tie.
"We'd love a massive tie but we can't think about that. We've got Torquay."
Evans believes his players must be at the top of their game to come out on top.
"I don't think the Torquay boys will think they can just turn up and win," he added.
"They'll know it's game on. This is a cup tie that could go either way.
"If we go there and perform as best we can, we will win. If we perform averagely, we'll lose. That's how fine a line it is."
The Blue Square Bet Premier leaders will take inspiration from their two previous giant-killing feats in this season's competition.
They beat League One side Swindon in a second round replay and overcame Championship outfit Derby County in the third round.
We want Torquay to be another magical moment

"The winning goal at the end of extra-time at Swindon and the goal in the last minute against Derby sit up there with the best of them," Evans continued.
"You take them to the grave with you. They're with you forever. You don't have to re-look at a DVD to see them. We want Torquay to be another magical moment."
