"It's very difficult for the Bosnians. They just need a little spell on the ball but every time they get it Argentina are forcing their heads down."
Chris:, external What an unfortunate start for Bosnia. I feel really bad for Kolasinac, that was very unlucky.
Argentina hold a fantastically high line from a Bosnia free-kick, before goalkeeper Sergio Romero is called into action to punch clear a cross/shot from out wide. We've seen nothing of Lionel Messi or Edin Dzeko yet.
There have already been more own goals in the 2014 World Cup (three) than there was in the entire 2010 tournament.
The World Cup of goals continues then. Raining goals in Brazil, and long may it continue.

Former England international on BBC Radio 5 live
"It was a good free-kick from Lionel Messi and Sead Kolasinac does not know anything about it. It just came through a crowd of players and what a bad start for Bosnia."
Recover and move on Bosnia. Brazil came back OK from conceding an early own goal after all.
Well that didn't take long! Argentina lead through an own goal...
Lionel Messi whips in a free-kick from out on the left, Marcos Rojo gets up to win the header and it hits the unfortunate Sead Kolasinac behind him before finding the back of the net. Bosnia's debut is a nightmare...
Argentina are playing a back three with Pablo Zabaleta and Marcos Rojo pushed right on at wing back. Lionel Messi doing his thing, flitting and floating around up front.
We are away in the Maracana...

"What a fantastic atmosphere. This is the kind of game that only the World Cup can bring about. Argentina, many people's favourites to win the tournament, against Bosnia, a debutant team."
The Argentina fans are making a tremendous din inside the Maracana. It's like Selhurst Park on a Monday night...
Juninho
Former Brazil and Middlesbrough midfielder
"The Bosnia players have to enjoy. One way or the other Lionel Messi and Angel Di Maria will find a way to the ball, so you have to attack. The way that Argentina play now has given Messi more freedom and I think they are going to prove why they are, in theory, the best team in the tournament."
James:, external Think Asmir Begovic will be busy tonight. But he has been busy all season for Stoke and was brilliant!
Former Argentina playmaker Juan Sebastian Veron: "The press demanded that Messi played the same as he did for Barcelona but that is difficult as they are two completely different teams.
"I think that captains have different ways of serving their captaincy. People like Leo do their talking on the pitch.
"Hopefully he will be great and can withstand the immense pressure on him."
Bosnia's anthem has no words. They only have a few fans in the vast stadium but they do their best to make themselves heard. A great moment in the relatively new country's history. Here we go then...
Tim Vickery
South American football expert on BBC Radio 5 live
"Lionel Messi and Sergio Aguero are sharing a room throughout this tournament. They are firm friends, fantastic relationship off the field, telepathic on it."
Vignesh:, external Just realized Miralem Pjanic also plays for Bosnia. Asmir Begovic, Pjanic and Edin Dzeko. Bosnia have the players to turn it on.
Anthem time. Argentina's Himno Nacional is absolutely roared out. Spine-tingling stuff in Rio.
Lionel Messi is a picture of concentration. He wasn't born the last time his side won the World Cup in 1986.
A great roar greets the sides at the Maracana. This is what the World Cup is all about. The biggest names on the biggest stages.
