Following a 5-0 thrashing away at Manchester City last weekend, Burnley were again humiliated by Chelsea, though Dyche believes Burnley were slightly unlucky in today's game.
"We started very well, on the front foot, with some good quality, good energy. We gave the ball away too cheaply [for the first goal] which we hadn't done up until that point.
"But on reflection, we've played two top sides the last two weeks and they've delivered top performances, and it's very difficult when they do that.
"You need them to have a quiet day and you to have a top day and I don't think today we were a million miles away with our performance, but we got punished four times and three of those were very good play from them.
"In the seasons since Leicester threw the form book out of the window, the superpowers have moved forward, they've spent more and built bigger squads, so I think it's getting more difficult.
It's a return to the norm. The only anomaly is Manchester United, but there is a reason why those teams are up there and in the form Chelsea and Manchester City are in, they are very hard to stop.
"There is some comfort in not playing Chelsea and City every week, but the Premier League is tough. These guys are really pushing the margins, you have to catch them on a quiet day and get the decisions. I wasn't too disgruntled with how we were today, but they were very good."
