"It was a nice relaxed start really," McDermott, talking to Reading's official website, joked.
"We were 2-0 down with eight minutes to go and (Mathieu) Manset has come up with two fantastic finishes.
"The second one was really good and it came just after Jobi McAnuff had hit the post. Another team would have thought that was it, but to give credit to the players they kept going and showed fantastic resilience."
"I've seen them in pre-season, any of Kenny Jackett's sides are very difficult to play against." he added. "They've got some quality in their team and Ken will be disappointed because they were 2-0 up with not long to play. But they're going to be up there this season."
“At 2-0 up Ken would've expected his team to see the game out. But credit to our players, there's a real resilience about them."
Lions boss Jackett refused to feel too downbeat with the outcome.
"That was disappointing but, having said that, I don't think we necessarily did enough to get a clean sheet," he told his club's official website.
"They were very good going forward and they always have goals in them. When you've got the frontline they've got, with four good players and players to come off the bench, that's what we're aspiring to, I think that's the next stage.
"There's a lot to be proud of. There's some frustration because it was a winning position but we got a little look at one of the best sides in the division."
