Call a public array from Main class on another class

Here’s the simplified code of what I am trying to achieve:

//Main.as

package {
    public class Main extends MovieClip {
        public var teams:Array = new Array("Brazil","Germany", "Spain");
    }
//later on code...
var simulate:Simulate= new Simulate();
addChild(simulate);
}

//Simulate.as

package {
    public class Simulate extends MovieClip {
        public function Simulate():void {
            trace("inside class"); //<-- working
            trace("team from Main.as" + MovieClip(root).teams[0]); //<-- not working
        }
    }
}

Any ideas?
Thanks a lot in advance!
