Luiz: Brazil's World Cup 'war' not over yet

The defender, who converted the first spot kick of the penalty shootout, says he remained calm during the tense climax and insists he will overcome fitness issues
Penalty hero David Luiz has warned Brazil not to let up on its World Cup "war" following their a spot kick victory over Chile on Saturday.

The Paris Saint-Germain defender fired the Selecao into the lead shortly before the 20th minute, but Alexis Sanchez equalized for Jorge Sampaoli's men just after the half-hour mark.

What followed was a scintillating match which could easily have swung either way. Hulk scored in the second half but saw the goal ruled out for hand ball, while Mauricio Pinilla hit the crossbar in the final seconds of extra time with the score still at 1-1.

Luiz converted the first penalty for Brazil in the shootout, which Luiz Felipe Scolari's men ultimately won 3-2, and he hopes he can shake off any niggling fitness worries to feature against Colombia or Uruguay in their World Cup quarter-final.

"I always practice penalties, with time you learn that should remain calm in these situations above all," he told SporTV. "Thank God, I was blessed.

"I'll have time to recover my fitness, I'm sure I'll be at 120 percent for the next match. I'm in the hands of very competent people, they will help me with that.

"One more battle is won, but the war is not over."

Brazil is hoping to avenge the last time it hosted the World Cup, in 1950, when it lost in the final to Uruguay.
