Manchester United manager Louis van Gaal says he'll continue to play Wayne Rooney in different positions depending on the opponent.

The Red Devils captain played in a midfield role in their 3-0 win over Liverpool yesterday - but still managed to score the opening goal.

Teenager James Wilson started up front with Robin van Persie instead of Rooney. 

Van Gaal says Rooney is versatile - but joked he does have limits.
