Chicharito trains for the first time with Man Utd squads and Sir Alex warns him not to score....against Man Utd of course

Javier Hernandez is confident of making a splash in England.

Hernandez, 22, insists he can make an impact even though his fellow countrymen Giovani Dos Santos and Carlos Vela have struggled to make the breakthrough in England with Tottenham and Arsenal respectively.

United's first Mexican player said: "I have spoken to them and they are definitely happy for me and they know that this is the most powerful league in the world.

"They tell me to take advantage of the situation and I should thank God for the opportunity.

"I always try to see pressure in a different way - more like motivation. There are millions of people in the world who would do anything to be in my position and have this opportunity.

"It's an honour because I want to achieve big things. It's a very nice challenge and hopefully I will be able to contribute.

"I will always try to enjoy it because sometimes we focus so much on the achievements and our dreams, and maybe we forget to enjoy it."

Hernandez admits he's still adjusting to being a Manchester United player.

Hernandez is pinching himself at the prospect of being on the same pitch as players he regards as legends like Ryan Giggs and Paul Scholes.

"These are people I would watch on the television, that I would even play with them on PlayStation," he told Major League Soccer's Spanish website.

"I dreamed of one day being able to play with all of them and I'm going to try to learn from them the most I can.

"Besides wanting to do the best job I can, grow and learn plenty, I also want to add my little grain of sand because this is a team sport. I want to win a title. I want us to be a great team."

Sir Alex has 'warned' Javier Hernandez ahead of his glamour return to Chivas.

After the MLS All-Star Game, United end their tour against Chivas in Guadalajara, where Hernandez will play a half for each side.

Asked what happens if his new player scores against United, Ferguson said: "He'll be fined and transferred back!"

Meanwhile, Ryan Giggs admits he'd never heard of new teammate Javier Hernandez before Manchester United swooped for him.

Earlier this year, he set a Mexican league record with Guadalajara with eight goals in the first eight games of the season.

"I didn't know too much about him before the World Cup," said midfielder Giggs. "After we signed him, I took an interest. Just like the fans, players are excited when you sign new players. He scored two very good goals in the World Cup and as a forward player, I'm excited to play alongside him."
