Gary Cahill’s tenth-minute header was enough to seal the victory for the Blues in California, despite having to play the game with ten-men for 20 minutes, after Cesc Fabregas' dismissal.
"When two great teams face each other in a game, nobody wants to lose and for this reason I saw a competitive game," the Italian told Chelsea's official website.
"I am pleased with the attitude today and also that when we played with 10 men we didn’t suffer. Don’t forget we are working very hard with two training sessions every day and it is a good attitude.
"The most important thing today was to see the right spirit in my team and the will to fight to win a friendly game. This is the right way."
The former Italy manager was also asked about John Terry, who played the whole 90 minutes alongside goalscorer Cahill, as well as Juan Cuadrado's role in the team.
"John Terry is the captain and he is working very well, like the other players," he added. "I am very happy with his attitude and I know he loves this team and this shirt. It is very important because he can transfer his passion for this club to the other players. He can play an important role this year if he plays and if he doesn’t play.
"With Juan Cuadrado, in my idea of football I love the role of the winger when doing a one-v-one. Cuadrado is one of these. I am pleased to train him and when today you can have a substitution of Cuadrado and Pedro to replace Willian and Moses, it is good for Chelsea.
"Cuadrado is a Chelsea player and I hope he remains one."
