Brazil defender Thiago Silva says keeping Tottenham striker Heung-min Son quiet will be key facing South Korea.

Brazil meet South Korea in the World Cup round of 16 on Monday.

"In terms of names, they are a tough side," said Chelsea defender Thiago Silva.

"They are players who are amongst the elite, like Son.

"They have a lot of quality in terms of passing, and defensively they are strong. They are good on the counter."

Gabriel Jesus and Alex Telles will miss the remainder of the World Cup, with Thiago Silva saying Brazil will now play for their injured teammates.

"Yesterday's training session was very hard, but at the same time our objective is to continue for them as well," Thiago Silva said.

"It's how we can comfort them a little. I hope they can recover as quickly as possible.

"It's good to see Neymar and Danilo on the field and Alex Sandro improving."
