Chicharito has joined up with the Mexico squad in the USA to play in his first Gold Cup, which begins with a clash against El Salvador in Arlington, Texas on Sunday.
And at a press conference he summarised his 2010/11 campaign for the Reds, but warned that his focus would be entirely on El Tri thereafter.
"Out of respect for my club and the Mexico team, I will not touch the subject of United from now on, but you can ask what you want today," he stated.
"This first year represents a lot for me and I am very grateful to God, because it was my first year in Europe and that was a dream.
"It has been surprising because I was not expected to play much, never mind score goals. So simply being able to play 90 minutes in my first year in a Champions League final against Barcelona is a big thing."
