Buenos Aires: What a difference a day makes. Or rather, what a difference a tactical overhaul makes, as Argentina showed in ripping Costa Rica to shreds to reach the Copa America quarter-finals.
Released from being a 'number nine', Lionel Messi revelled in being what he really is - namely, a striker who likes to attack from deeper, leaving real centre forwards in front of him.
Argentina are, as coaches and players past and present have lined up to hammer home in recent days, not Barcelona. But, as Diego Maradona pointed out before the Costa Rica game, that fact - and draws with Bolivia and Colombia - do not mean that Messi is not the greatest footballer on the planet.
