Chelsea seemed to be cruising to victory thanks to goals either side of half-time from Juan Mata and Frank Lampard.
But Le Fondre had other ideas. The former Rotherham striker came on with little over 20 minutes left and yet again made a crucial impact, beating Ross Turnbull first in the 87th minute and then 50 seconds from the end of stoppage time to hand Reading a vital point.
"The two finishes from Alfie (Le Fondre)...," McDermott 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 this season after scoring six of his goals after coming 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."
