Brazil captain Thiago Silva says Cameroon striker Samuel Eto'o is the striker he is most concerned about ahead of the World Cup.

Script:

SOUNDBITE (Portuguese) Thiago Silva, Brazil captain (On which forward concerns him most):

"Look, I can talk about (Samuel) Eto'o. I played against him recently and also faced him when I was at (AC) Milan playing against Inter Milan. I know how skilful he is. A very skilful, experienced player. I believe he's stronger now. In the (UEFA) Champions League, when we were knocked out by Chelsea, I believe he was not 100 per cent fit. Yet, he made a lot of trouble for us, on the defensive side. Even hit my ankle, hurting me a little bit. He's a very, very skilful player, impressive. If you give him just a small space, he's a killer. You can't blink."
