Brown has been struggling to force his way into the first team at Old Trafford due to a niggling run of injuries.
“I have been injured on so many occasions, I am used to coming back and trying to getting back into the team,” he said.
“That has happened again this season. The injuries have been frustrating but this is the only place I have ever wanted to be and Manchester United is the only club I have ever wanted to play for.
“I am still happy to do that.”
