Manager John Hughes was full of praise for substitutes Ryan Christie and Aaron Doran following a 2-1 victory for Inverness at Dens Park.
Dundee led at half-time through Greg Stewart's finish but Billy MacKay levelled and Christie forced in a late winner as the visitors finished strongly.
"They should be first-team regulars but the team's been on a good run," Hughes told BBC Scotland.
"They train hard and you can see the talent the pair of them have and it won't be long before they are back in the starting 11.
"We're grateful that we have stayed clear of injuries because we have a small squad but these guys that are coming on are all technically very good footballers.
"They can score goals, they can link up, they combine and thankfully, in the last five minutes, they combined to get that goal."
Dundee faded after the break while Inverness grew in strength after MacKay's scrambled finish, while Christie's goal also came from a goalmouth scramble.
"I'd have taken a point here after going behind but we've got good legs in the team and we kept going.
"I don't think it was a great game; two teams cancelling each other out. Although we weren't at it, I said at half-time we can go up a couple of gears.
"I know my players can pull it out the bag.
"And you know what they say, if you're not playing too great, dig in and win, it's a sign that you are not a bad side.
"I'm delighted with the three points. For me, it's December and January that tells you where you're going to finish."
Dundee boss Paul Hartley was disappointed to see his side fall out of the game after getting into a winning position.
"I thought we were going to get a point at least," he said.
"We were excellent in the first half the way we stopped Inverness from playing. But we stopped off it a wee bit in the second half.
"We lost two poor goals. Inverness didn't work hard enough for the goals they got. We didn't defend the crosses and didn't stop runners coming into the box.
"The second-half performance compared to the first was night and day.
"But there are no excuses. We go to Hamilton next week for a really tough game so we have to lift ourselves for that. We will work hard in training this week to correct what we did wrong here."
