Javier Hernandez is happy at Manchester United, according to Steve Round.

David Moyes has been handed yet another selection headache by Javier Hernandez after the Mexican took his tally to three goals in a week to help guide Manchester United through to the Capital One Cup quarter finals.

United defeated Norwich 4-0 in a sign that their confidence is returning and the scoreline was largely in part thanks to Hernandez's brace.

The Mexico international has scored the winning goals for United on a number of occasions since moving to the club in 2010 but Sir Alex Ferguson often treated him more as a super-sub rather than a regular starter.

Moyes has equally been cautious of starting the striker over the likes of Danny Welbeck and Robin van Persie, prompting possible exit rumours, but assistant manager Steve Round has insisted that the 25 year old is happy to fight for his place at Old Trafford.

"He's such a good character that I don't think it's fazed him at all. He knows he gets his games and gets his opportunities," Round told reporters.

"You see in training every day that he's a really infectious character who loves to score goals. His history is at Manchester United, he's waited patiently for his opportunities and when he gets them, he takes them."

Hernandez also contributed to the win over Stoke at the weekend, scoring the third goal for United tosnatch a 3-2 victory and save their blushes after being 2-1 down at one stage.

And Round suggested that in the future, despite Moyes appearing to prefer Welbeck, he will likely use Hernandez in combination with Van Persie and Rooney after their recent successes together.

United's number two explained: "They finished like that on Saturday, so there might be games where that might transpire, but it just all depends on what the manager's game-plan is, who we're playing, and how he wants to put a team out."
