The 20-year-old made an impressive debut in United's 3-1 friendly victory over Chicago Fire and has admitted that he is learning the English language to help him settle in as quickly as possible.
"I'm slowly getting used to life here," the goalkeeper told MUTV.
"There's some players I can speak to. Some of them speak a bit of Spanish and I'm learning English little by little and communicating better with the team.
"It's difficult but I'm young and, in few months, when I've learned some English, I will be able to communicate perfectly with others."
De Gea cost United £18.3m earlier this summer.
