A driving run from Hulk, who is pulled down by Eugenio Mena. The big man gets up and attempts to gee up the fans. He is up for this.

Brazil have a very dangerous looking free-kick but Neymar's curling effort is headed clear.

"This is the moment when you are walking around trying to gee your team up and get your energy back in your legs for extra time. This moment right now is very important."

"The scene right now looking down on the Maracana. No noise from surrounding flats as Brazil fans await extra time."

Ready? Here we go.

Brazil have had their lowest passing accuracy, 66%, in any World Cup match since 1966. They need to improve.

A very energetic Luiz Felipe Scolari gives his instructions to his players while Chile's boss Jorge Sampaoli paces away like a caged tiger.

"I think it was the right call [to deny Hulk the goal] - it hits the top of his arm. How could Howard Webb see from where he was?"

Ben in Coventry via text: I hope this game does not go to penalties, there's no room on my wall chart to include them.

"Alexis Sanchez has been incredible for Chile - he's dominated Brazil's back four."

Kevin Kilbane
BBC Radio 5 live

"Chile had that glorious opportunity when Julio Cesar made that brilliant save but it is a very tense stadium. Both sides did not really show too much attacking intent in the final 10 minutes."

The final whistle is met with a nervy silence by Brazil's fans. They have another 30 minutes of tension to be put through.

Brazil should be celebrating the win having had the better chances throughout but a mixture of bad finishing, good goalkeeping and bad luck mean Chile are still well in this.

It would take a brave man to call this now. Anyone?

Conor McNamara
BBC commentator

"The commentary on Brazilian TV at the moment sounds like the sombre tones of a state funeral."

Cathy in Northampton via text: "Come on Chile. Blow this game wide open. This Brazil team have a horribly entitled air about them."

Alexis Sanchez's right-wing corner is flicked clear by Dani Alves.

Wait a moment, corner for Chile......

David Ornstein
BBC Sport in Belo Horizonte

"The Brazil fans have been calling for the introduction of 21-year-old Belo Horizonte-born winger Bernard, but coach Scolari only has one more substitution to make and he needs to be careful how he uses it with extra time and possibly penalties looming."

Jason Mohammad
BBC Sport presenter

"Big Phil. Big decisions. Fans not happy here."

Brazil have a throw deep, deep inside their own half. It is going to take something special to win the game in normal time now.

Alexis Sanchez goes down on the edge of Brazil's penalty area. No foul and Brazil break before giving the ball away. Three minutes of injury time to be played.
