Twelve months ago, Chicharito scored his first goal for United as part of their tour of the US.
"Pre-season is very important and you need to work hard in order to start the season well," Chicharito told ManUtd.com.
"The facilities in America are wonderful and the coaching staff worked really hard to help us improve."
The young Mexican holds a great affection for America, given that was where his United career started with a bang.
"I have so many great memories of last year's pre-season tour," he said. "It was the first chance I got to meet up with the team, I had my first training session and played my first match.
"I remember everything about the experience very well, especially my first game. There was a great atmosphere in the stadium. We won the game 5-2 and I managed to score."
