Javier Hernandez admits he's had a frustrating season so far at Manchester United.

The Mexican striker's appearances this term have been limited due to a combination of injury and Danny Welbeck's outstanding form.

"It has been a little bit frustrating because I have been injured a lot," he said.

"But there are some things you can't do anything about.

"I am happy and I am still enjoying it. It is a privilege to play for Manchester United, whether things are going good or bad, I want to keep that attitude."
