Chelsea boss Mauricio Pochettino was happy to see Nicolas Jackson and Mykhaylo Mudryk score in victory over Brighton.
The Blues won a thriller in Philadelphia.
"We are happy for the fans; they enjoy a good game," Pochettino said.
"Of course, a coach is never happy when you concede goals, but it's normal because it is only two-and-a-half weeks to work and evolve the different areas of the team.
"I am happy, I saw many positive things. I am so happy with the attitude of the players and the staff. We showed great attitude and energy against a team that did a fantastic job last season.
"I am so happy with the balance in these two-and-a-half weeks. We know we have to work a lot and continue to improve. But we're starting to see certain principles that will be very, very important for us."
Pochettino continued: "For Jackson and Mudryk, it's important to score. Nkunku also. Attacking players need to score to get their confidence and trust themselves. It is important to score goals and then we try to improve.
"Today, we maybe had more capacity to stay calm and create more chances and score more goals. These areas we have to work, we're going to focus our work. It takes time to believe and trust in the process to arrive in the best condition."
