Reading are still without a win in the Barclays Premier League this season and remain in the bottom three.
When asked what pleased him with the result, McDermott said: "Keeping a clean sheet, obviously.
"I'm not disappointed, we have had a few disappointments this season, when we were winning at Arsenal and 2-0 up at Swansea.
"But I can't be disappointed with the group of guys that have given us absolutely everything. In that dressing room they are disappointed themselves but there is no need to be.
"Everyone is talking about the win, we have just got to concentrate on the game and that is all we can do."
