The 51-year-old put his side's poor performance down to a lack of match practice as the Royals played their first match since August 22, going down to a loss against Spurs
The Royals were playing their first Premier League encounter since their trip to Chelsea on August 22 and found themselves overrun in the first half, struggling to impose themselves on the visitors.

"In the first half we weren't ourselves for whatever reason," McDermott told talkSPORT. "We can talk about the fact that we haven't played for 3 weeks but the good thing is we've got that game under our belts.
"We haven't played for such a long time in this league so it took us 45 minutes to really get going and we were 1-0 down, still in the game.
"My regret - and I hate having regrets in football - is that we didn't give them the game that we know we can do."
