Lionel Messi and Sergio Aguero aim to strike gold again as Argentina take on hosts Chile in tantalising Copa America 2015 final 

With their floppy locks and childish grins, Lionel Messi and Sergio Aguero had not a care in the world and that same world at their feet.

Clutching gold medals on the Beijing running track after their Olympic triumph, the close friends appeared destined to spearhead the next great Argentina side.

But seven years, two World Cups and a Copa America later, they have yet to emulate that success.

That could all change on Saturday evening however as the pair reunite in Santiago for the final of the 99th edition of the South American tournament.

Indeed, assuming Ezequiel Garay recovers from a stomach bug, seven of the side that started that Olympic final in 2008 will do so against Chile.

Argentina take on the hosts at the Estadio Nacional fresh from their 6-1 mauling of Paraguay in the last four.

That smoggy evening in Concepcion was dominated by the three amigos: Messi, Angel di Maria and Javier Pastore while Aguero chipped in with his third goal of the competition.

And there were sufficient signs to suggest that manager Tata Martino has stumbled upon the winning formula.

Stumbled, because if X had marked the spot, his predecessors would surely have discovered gold long before now.

At last summer’s World Cup in Brazil, three victories by a single goal in the group stage were followed by an extra-time win over Switzerland. Belgium were also beaten by one and a penalty shoot-out was required to see off Holland.

Argentina’s better-than-it-looked run was finally halted by Mario Gotze’s Germany in the Rio final before Martino took over from Alejandro Sabella.

Not that their Copa America campaign has been plain sailing, with Paraguay’s second-half comeback in the opening group game a reminder of their shortcomings.

But in their subsequent three matches, they faced teams who had only a plan A: to defend.

Uruguay and Jamaica were beaten 1-0 before a dominant performance against Colombia was only rewarded after an epic penalty shoot-out.

Not until Paraguay opened up in the second-half last Tuesday, did Messi and Co slip into gear and run riot.

Which makes tonight’s clash with Chile nothing short of fascinating.

Jose Sampaoli’s side have a plethora of attacking options of their own in Alexis Sanchez, Jorge Valdivia and Eduardo Vargas, backed up by Arturo Vidal.

La Roja will cause Martino’s men more problems in the final third than they have thus far encountered in the tournament.

But until Peru were reduced to 10 men in their semi-final, Chile struggled with the pace down the flanks. And Jefferson Farfan is no Lionel Messi.

To that effect, reports in Chile this week suggested players, including Sanchez, have been using a Playstation 4 to work out how to stop the Barcelona maestro.

Captain Claudio Bravo, however, insists there is more to their opponents than his club team-mate.

‘The truth is that it is not easy, seeing the quality that Leo has and what he has done throughout his career, it’s been amazing,’ he said. ‘I think our focus is the team – that as a team we can control Leo and the other class players.

‘Javier [Pastore] is a very valuable player who gives character to your team, is the heart of the side.

‘[But] the performance of the team does not only go through Javier or Leo.’

One option for Sampaoli is to revert to five at the back as he did so successfully in friendlies against England and Germany and against Spain at the World Cup.

That could mean sacrificing playmaker Valdivia who has been instrumenta over the last month.

And not only is the pressure on Sampaoli as manager of the host nation but as the guardian of the finest generation of footballers Chile has produced.

They have never tasted major success, something that cannot be said even of minnows Bolivia and Peru.

One way or another, one nation’s drought will be quenched come full-time.

‘I always said what happened at the World Cup… kept a thorn in me,’ admitted Aguero. ‘We will always have a bitter taste from the final with Germany, but winning the Copa would give us much happiness.’

And for the Manchester City striker and his international room-mate and friend, it would be not a moment too soon.
