The Clarets played twice a week since the season started as they took part in the Europa League qualifiers, eventually losing at the last hurdle to Olympiakos.
And the manager believes it was too much for his crop of players.
"Well, I think we're finding our feet a bit," Dyche commented. "They've had a lot of challenges these players.
"It's game 10 for us of a squad of roughly 17 at any given time. We were down to 16 on Thursday and that's a lot of football for anyone in this early part of the season.
"It's still physically a task. This two-week period now gives us a chance to rest and work, but certainly refresh ourselves for the challenge which is the Premier League."
