The goals of N & # 39; Golo Kante and Pedro came on both sides of a penalty of Jorginho in the first game of Sarri in the Premier League in charge of his new club.
While the score suggests that the victory came in a very unilateral competition, the new boss suggested the opposite.
"The game was more difficult than the result," Sarri said after the game at John Smith Stadium.
"If you see the result, you think it was a very easy game, but in the first half it was very difficult against physical opponents.
"The game was more difficult than the result"
"We are not a physical team, so for 20 minutes we had problems, but we did very well.
"At the moment we are not at the peak of our potential, but we had the ability to suffer for 20 minutes in the first half."
After replacing former boss Antonio Conte later in the summer, Sarri has not had as much time to work with these players as he would like.
That, along with the fact that several players have just returned to the club after their World Cup efforts, means that the preparations have not been perfect.
After the game, they interrogated Sarri about the time he thinks his squad will take to reach the level he requires.
"It depends on me and the players, I do not know," he replied.
"The situation so far has been very difficult, and four World Cup players arrived on Monday.
"And then on Tuesday, two more, so it has not been easy for me at the moment, with luck two months and not three."
Chelsea still started the game with several players who participated in the World Cup.
Midfielder Kante, who won the tournament with France, reached the starting line even though his compatriot Olivier Giroud did not arrive from the bench.
The star man Eden Hazard, who reached the semifinal with Belgium, made a late appearance when he replaced Willian, who played for Brazil in Russia.
Huddersfield manager David Wagner was pleased with the performance of his team, but admitted that the fact that Chelsea was finished was the difference.
"I think Chelsea was very clinical," he said. "They had four or five opportunities and they scored three, we started very well in the first half, we pushed a lot and the players did very well.
"We had a very good chance at 1-0, where Steve Mounie hit the post and instead of being a goal we were down to a goal and just before the break we made a tactical error to award a penalty."
