Javier Hernandez insists he is happy just to be playing as he prepares to start for Mexico.
The Manchester United striker has started just four Premier League matches this season under David Moyes, and has expressed his frustration with the situation.
The 25-year-old has linked up with Mexico ahead of their friendly with Nigeria in America on Wednesday.
"I am very eager to play as my club don't take me much into account. I hope I have the opportunity to play," he told Record.
"When you are called up, you have to be thankful and if not called up, you have to keep working. I am very happy and thankful with this call-up, like I was when I was called up for the first time."
Mexico take on fellow World Cup qualifiers Nigeria, and Chelsea defender Kenneth Omeruo - on loan at Middlesbrough - thinks it is an important game.
"It's definitely a good game because playing will help us both toward the World Cup," he said.
"It will be a good game and we hope to win, we know that Mexico has great players playing very well and this match against Mexico will not be easy."
Omeruo feels that Hernandez is their main threat, and added: "I think he is a good player, with great quality and I think he is the hope of Mexico."
