Former England footballer Rio Ferdinand at the Maracana

On marking Edin Dzeko: "He is big but the thing that sticks out for me is his movement. When the ball goes wide he comes alive and he can be out of the game but then score."

On marking Sergio Aguero: "He's been my hardest opponent to play against. He is quick, strong and direct. When he gets you stood up he can go either side and that is not good for a defender."

On marking Lionel Messi: "He is one footed but he can go either way as well. The thing about him is he is cute upstairs and is a threat with or without the ball. He can take you into areas you don't want to go. He will make a run and ask you the question of whether you want to go and mark him."

The sides are in the tunnel.

Lionel Messi looks a bit uptight, while Bosnia captain Emir Spahic is beaming. He is loving it and quite right too...

Former Argentina defender Gabriel Heinze on past criticisms of Lionel Messi: "It was silly because the press even said Leo didn't want to sing the national anthem.

"Personally, it made me laugh when the same journalists would later say wonderful things about Leo."

"Asmir Begovic is an outstanding goalkeeper and I think Stoke will do well to keep hold of him. I am sure, if he has a good World Cup, there will be people talking about him and maybe putting bids in."

What a game Angel Di Maria had for Real Madrid in the Champions League...

Josh:, external Angel Di Maria is the most improved attacking player n the world this year with Real Madrid. I can see him bagging plenty in Brazil.

How will three at the back suit Argentina? We are about to find out.

Kick-off is 10 minutes away. Don't go missing Lionel...

"It is a magnificent achievement for Bosnia-Hercegovina to be here so anything else will be a bonus. I think they can get out of the group even though they have a tough first game."

Neil Lennon
Former Celtic manager

"You can sense what playing for Bosnia is going to mean to the players, it will be interesting to see their faces when the national anthem is played. It is a very proud nation who have suffered a lot, it is amazing what football can do."

"Edin Dzeko is a talisman for them, he is in the form of his life after a brilliant season for Manchester City. Bosnia scored 30 goals in qualifying and he scored a third of them. Dzeko is the go-to guy tonight. I think they are a really dangerous team."

"In 571 minutes at World Cup finals Lionel Messi has scored just one goal, the same number as Matthew Upson and Gary Breen. In 754 minutes, Cristiano Ronaldo has only one more than the England and Ireland centre-halves.

"To put that into goalscoring context, Denmark's comparatively prosaic forward Jon Dahl Tomasson has five. Pele ended with 12, and the Brazilian Ronaldo had 15."

"A new manager comes in for Argentina, gives Lionel Messi the captaincy and he responds with 10 goals in 12 games and that shows even the best players need to be loved.

"It is a massive tournament for him. He is the best I have seen in my time. What he can do with a football, he can go either way and is a nightmare for the opposition."

Tim Vickery
South American football expert on BBC Radio 5 live

"It is interesting because Argentina's base system in qualifying was 4-3-3 set up to give Lionel Messi as much space as possible, so why has it been changed to 5-3-2? Previously, when the manager Alejandro Sabella has used this formation it was when he did not have Messi. So why use it tonight?

"Perhaps Sabella is feeling the pressure a bit. Despite his age he has very little experience, and I don't think he is enjoying the job. He was a bit tetchy in the news conference yesterday so maybe he has gone for something a bit more defensive.

"He has said before that when his team is attacking he closes his eyes and prays, because they can be a little exposed defensively, so perhaps he has gone for a more protected backline so he can keep his eyes open."

Harry:, external Looking forward to seeing how many goals Argentina put past Bosnia. Lucky it's on after the watershed!

Charles:, external Looking forward to seeing Argentina play, and newbies Bosnia Hercegovina, hope they don't get hammered.

Manchester City fans may have split loyalties this evening.

There's nobody more popular at Eastlands than Pablo Zabaleta, who starts, while Sergio Aguero is also in the Argentina team and Martin Demichelis is on the bench.

Across the park, Edin Dzeko - scorer of so many vital goals in the title run-in - starts up front for Bosnia.

Neil Lennon
Former Celtic manager

"Playing against Lionel Messi you have to try not to be too emotional, stay on your feet as best you can. He has got unbelievable pace, he sometimes seems to be on the periphery of games but when the ball comes into his feet, what an unbelievable player."

Juninho
Former Brazil and Middlesbrough midfielder

"For Brazilians, when you play against Argentina you must win, if you don't win, then don't come back to Brazil, better to wait a few days!

"32,000 Argentine fans have come to Brazil, flying, by car, or by bicycle. We welcome them, but on the field I think the Brazilians will support Bosnia."

Rio is teeming with Argentine fans tonight. It could be a cracking atmosphere for what is Bosnia's World Cup debut.

We are back live on BBC One and at the top of your page. Get set for the Maracana...
