Manchester United boss Louis van Gaal admits Rafael has been fit to play for the past week.

Van Gaal, however, says the fullback is yet to warrant selection.

"Rafael is not injured," the boss explained. "He was already fit last week, but I have to select and I have to compare.

"When I have more players fit, I have to select. You will have to wait and see, of course. I have to compare. Rafael? I can take him in the 18."
