It was an impressive display after less than a week of training and although he said he didn't want to highlight individual displays, Mourinho was clearly pleased with new arrivals, Jose Callejon, Fabio Coentrao and Rafael Varane.
"Coentrao made an important contribution and that will help him adapt to the side and he had a good game. Callejon played well and Varane had a comfortable match and that is important. The new signings have shown that they have the legs to help carry this project forward," said Mourinho, after the game in the Memorial Coliseum in Los Angeles.
The Portuguese coach refused to be drawn on what titles his side would be able to win in the forthcoming season after last year they won the Copa del Rey, but were defeated by FC Barcelona in both the Primera Liga and the Champions League.
"The differences between winning and not winning trophies are in the small details, In my first year we did well for a young team and a new squad," said Mourinho, who clearly hopes for better this time around.
"We are working well, we played with two good sides today and we still have Gonzalo Higuain, Angel de Maria and Nuri Sahin to come. We are working better all of the time and we will be there to compete. We are working with ambition and hoping to iron out the details. I don't promise titles, just work," concluded Mourinho.
