Rooney's preparations for Friday night's Euro 2012 qualifier in Podgorica have been disrupted by news that three members of his family, including his father, have been arrested as part of a Merseyside Police probe into suspicious gambling during a Scottish Premier League match last season.
But Vucinic said: "Rooney has everything.
"He can run and shoot. Every chance he gets, he scores. That's the most important thing.
"But he can't do anything without the ball at his feet. We have to try and stop him from getting it."
