A brace from Kei Kamara either side of Federico Higuain's 49th-minute effort gave the Crew a 3-2 triumph over the Sounders in Ohio on Saturday but despite the magnitude of the win, Berhalter was simply moving on to the next fixture.
"It's business as usual," Berhalter said after the match.
"I'm obviously pleased with the game, the way the game was played. I told the guys to go out and entertain the fans and the people watching, and I think they did that.
"But as far as we're concerned, we know [Seattle] are a good opponent, but it's just another game."
The win lifted the Crew to third on the Eastern Conference table, getting them back on track after a disappointing defeat at DC United last week.
