Right, before I'm in danger of running out of things to waffle on about, and more of a test to see if you are indeed awake than anything else, it's time to call upon you input.

Which star you think will shine brightest at the tournament?

Will Lionel Messi step up to the plate and lead Argentina to victory? Neymar to help Brazil to make up for their World Cup disappointment? Will Colombia and Real Madrid forward James Rodriguez star? Or maybe Arsenal's Chile star Alexis Sanchez?

Could Radamel Falcao give Chelsea fans reason to be optimistic, or is there an unfamiliar name who could steal the show? Let us know your thoughts via #bbcfootball or text in on 81111.

The Estadio Monumental in Santiago, Chile is the venue for this game, and the stands are filling up nicely with kick-off just a little under one hour away.

If you are unable to watch the game, then take solace in the fact you won't have to endure the below instruments of horror - the vuvuzela, spotted in the hands of some spectators making their way to the stadium.

Still, no half-and-half scarves on show, at least.

Yep, Brazil's players certainly made James Rodriguez know he was in for a battle at last year's World Cup, with the Colombia forward on the receiving end of a number of bruising challenges.

Revenge on the mind then, surely?

"It's not revenge, it's one more match, and I think it will be a good one," says Rodriguez. "Neymar is playing incredibly well but they're going to have to be good to beat Colombia."

Best not have a quick check of the history books then James. Brazil have lost just twice in 27 encounters between the two...

James Rodriguez. While it was a World Cup to forget for Brazil last year, it was undoubtedly one to remember for the Colombia forward.

The 23-year-old stole the show at the tournament, scoring six goals to win the Golden Boot and helping to earn him a move to Real Madrid.

He failed to shine in Colombia's opening game at the Copa America but, given the rough treatment he received against Brazil at the World Cup, he'll no doubt be keen to put on a show this time.

Hello! Not ready for bed yet? Good, because we've got the potential for come cracking Copa America action ahead of us. Fancy a bit of Brazil versus Colombia?

The Brazilians may well fancy their chances of picking up three points, but they were far from convincing in their opening game win against Peru, when they came from behind to win 2-1.

They are also up against a Colombia side who will want revenge for their quarter-final defeat to Brazil at last year's World Cup and will also be desperate for three points after a shock defeat to Venezuela in their first game.

Oh and they've got this chap to call upon too...

This was the moment that broke Brazilian hearts. Neymar, in tears and clutching his back, suffered a fractured vertebrae after a challenge by Colombia's Juan Zuniga that would rule him out of last year's World Cup.

It sent a nation almost into mourning, with even the president of Brazil saying her heart had been "injured" when she saw the look of pain in Neymar's face.

The pain was to get worse, Brazil suffered a humiliating 7-1 defeat at the hands of Germany to complete a World Cup to forget for the host nation.

Now they face Colombia again. Reinvigorated and boasting a fully fit, perhaps even deadlier, Neymar.

The World Cup was Brazil's lowest ebb, but will the Copa America be the tournament that sees them shine once again?
