SOUNDBITE (Spanish) Alejandro Sabella, Argentina head coach:

"You have to be very strong psychologically and emotionally. I always say that if the mind was a muscle then it would be the most important muscle. I think there is a philosopher who once said that one gram of brain cells is more important than a normal muscle in the body.

"I think both players (Neymar and Messi) are amazing players. Messi is the best in the world. Neymar is a great player. And, of course, with players like those the team depends on them. It is normal. Argentina depends on Messi and Brazil depends on Neymar. It is normal. Now, the supporters. I think the most important thing is that the supporters behave properly in the stadium tomorrow. And, until now, we have had many supporters from Argentina at this World Cup. We have many people at the Maracana, at Porto Alegre, at Belo Horizonte as well but we will see. Things could change. The most important thing for us is that people in the stadium behave properly and keep a peaceful atmosphere."
