McDermott was a picture of joy as he talked through Le Fondre's late double strike.
"The two finishes from Alfie (Le Fondre)...," the Reading boss said before pausing for breath. "...the second one was ridiculous. It was a top, top-drawer strike, and to do it at that stage of the game..."
Le Fondre has earned the tag of super-sub after scoring six of his goals off the bench.
McDermott insists the striker is happy with his role, although he did hint he may have to start the hitman after his prolific efforts in the Royals' last two league games.
"I speak to Adam as much as I can. It's difficult for me to pick a team," McDermott said.
"I do the best I can to try and get the right team to get the result.
"He's just a great bloke - that's it. He's funny, has real good banter. He trains like he wants to be the best player in training.
"Of course I'd start with him, but I'm trying to find a way to get results.
"The boy's happy, the team's happy, because of those last few results. I'm so pleased for him and them."
