Nigeria coach Stephen Keshi:
"Messi is one heck of a player. You can't take that away from him. He's blessed. I think there are other players in the Argentina squad who are very strong, but Messi is from Jupiter.
"We gave too much respect to the Argentines and did not play our game in the first half. We played a bit more aggressive in the second half. Congratulations to the Argentina team, I wish them all the best in the tournament."

Andy from Armagh on text: Both Argentina and Nigeria should be applauded for their willingness to play open, attacking football this afternoon, it created a brilliant spectacle for the fans. It has been a noticeable characteristic of this 2014 World Cup, and hopefully that trend will continue throughout the tournament.

Bahman Nooraei B:, external Bosnia deserved to go through much more than Nigeria. They'd have won the game vs #NGR if it wasn't for bad refereeing.

Former Premier League striker Jason Roberts
BBC Radio 5 live, Porto Alegre"That was a very enjoyable game. Argentina win it in the end with a scrappy set piece but they look vulnerable defensively. Whoever face Nigeria in the last 16 will have to deal with Musa. His pace will cause anyone problems."
