Argentina 1-0 Paraguay - Marcos Rojo
Image source, Getty ImagesFirst blood to Argentina as Paraguay fail to deal with a Lionel Messi free-kick into the danger area and Manchester United's Marcos Rojo produces a low finish from close range to give his side the lead. Paraguay have it all to do.

Argentina 0-0 Paraguay
Argentina have yet to really fire at this tournament scoring just four goals in four games. It's another cautious start by Gerardo Martino's men, who are wearing their traditional light blue and white striped shirts. Paraguay are playing in their familiar red and white shirts.

Quote MessageOne hazard of covering a football match in Chile, I've just got chunky guacamole all over my team-sheet! A large media turn out as you'd expect. The organisers have told us we'll have to go to the post-match mixed zone well before the final whistle. Let's hope it doesn't go to penalties! And talking of penalties...if Paraguay were to win on penalties, they would have reached the last two Copa America finals having only won one match in normal time. And that was against Jamaica!

Not something you see very often...Lionel Messi has the ball whipped off his toes and Paraguay launch a counter attack which ends with Roque Santa Cruz drilling a chance wide from 20 yards. An early warning for Argentina.

Not the free-flowing start we saw in Santiago in the other semi-final between Chile and Peru.
Very tight start, both teams eager to get a feel of the ball. Lots of neat passing, little goalmouth action.

Sulaimon Adelekan:, external Chile win the Copa America because they have been the best at the tourney so far.

Terrific noise in Concepcion.
Just enough time for Lionel Messi to land a pre-match peck on Sergio Aguero's cheek...and we're under way.

Argentina v Paraguay (00:30 BST)
Incredible but true.... Paraguay reached the Copa America 2011 final without winning a single game.
After drawing all three group games, they defeated Brazil and Venezuela on penalties in the quarter-finals and semi-finals respectively before losing to Uruguay 3-0 in the final.
This time round they have won one game to date - against Jamaica.

Quote MessageLet's hope the celebrations don't turn nasty like they did in the Plaza Italia in central Santiago last night. The Chile fans had to flee water canons and tear gas. Hopefully BBC World Football's Mani Djazmi (pictured above) will have a safer night reporting in Concepcion.

Paraguay's win bonus...published at 00:21
Argentina v Paraguay (00:30 BST)
Image source, ReutersFootballers have been rewarded with performance bonuses ranging from money to villas and holidays. But pick-up trucks? And not one, but three?
That is what awaits Paraguay's squad if they defeat Argentina.
"Did I promise the squad something? Ask the players, they've already won two," said the country's Argentine coach Ramon Diaz.
Striker Edgar Benitez added: "We've already won two pick-ups off him and we're going for the third."
Why Messi is clinging on to Junepublished at 00:19

It's now officially July in Britain but in South America it is still June - just.
And Lionel Messi just loves the sixth month of the calendar year...
Messi goal drought?published at 00:16
Argentina v Paraguay (00:30 BST)
Think Lionel Messi and immediately goals come to mind.
The 28-year-old can't stop scoring for Barcelona but for Argentina it's a different story.
Astonishingly, Messi has scored just one international goal in 828 minutes - that's more than 13 hours - of official matches. And that came from the penalty spot against Paraguay in his team's opening Copa America group game.

Time to hear from our man in Chile...
Quote MessageA return to the wood-smoke smelling Estadio Municipal in the university city of Concepcion. A rather charmless town if truth be told, but perhaps I'm missing something. A good number of Argentina fans have made the trip across the border, but still the chant of "Chi Chi, Chi, La La La, Viva Chile" is the vocal motif in the stadium...as the local residents have also turned out in force. And the tournament's volunteers are being extra helpful today, even carried my TV camera to my seat in the media tribune. After weeks of disorganisation, it seems Chile is slowing learning how to host a major sporting event.

Football...it's a funny old game.
Ten years ago Ramon Diaz was managing in League Two.
Now the 55-year-old Argentine is two matches away from leading Paraguay to their first Copa America triumph since 1979.

Argentina v Paraguay (00:30 BST)
Image source, Getty ImagesThese two teams are anything but strangers, their most recent meeting coming just over two weeks ago when Paraguay fought back from two goals down to deny Argentina victory in their opening group game of the tournament.
Argentina raced ahead in the first half as Sergio Aguero slotted in before Lionel Messi converted a penalty.
Paraguay fought back after the break, Nelson Valdez halving the deficit with a long-distance shot. Lucas Barrios then drove in late on to snatch a point.
La Albirroja will have to display all those fighting qualities again if they are to make it to the final.
