The Daily Star says Van Gaal is expected to make Robin van Persie his skipper next season.
The pair are close friends, with Van Gaal making Van Persie captain of the Holland team when he became national boss in 2012.
But the decision will leave Rooney fuming considering he wanted the role himself at Old Trafford.
Van Gaal knows he risks the wrath of fans before he has even started his new job and doesn't want to alienate the England striker.
