Two of the hot favourites for the tournament have reached the final, in what promises to be an exciting and tense affair as the host nation come up against last year's World Cup finalists. However, Chile have had their fair share of problems and controversy along the way with Arturo Vidal's car crash and Gonzalo Jara's unorthodox marking tactics against Uruguay, but with a raucous home crowd cheering them on, Chile will surely fancy their chances of lifting this title for the first time. Standing in their way is Lionel Messi, whose performance in the semi-final against Paraguay showed that he is in some of the best form of his career, and may well be on course to captain his national team to their first major trophy since he has become part of the senior squad. While Chile have been entertaining, their fast-paced, high-pressing game may well leave spaces for a team of Argentina's quality to exploit, and when Messi plays like he currently is, there's very little anyone can do to stop him.
