Ronaldo is always on the wing and always gets back on the wing after any move. Ronaldo will only move around during a move. He's most certainly a winger.
Ronaldo, Rooney, Tevez, Giggs (or whoever else the attacking quartet are) are continaully interchanging and moving about. I'd just classe them all as "attackers" these days, gone are the days of the very top teams playing a rigid 4-4-2 so its hard to pin down what a player should be labelled as.
A system that so far is yielding fantastic results and amazing play. Long may it continue
