Left back
As good as Marcelo is, Jan Vertonghen had to play out of his skin to be chosen ahead of the Brazilian and he definitely hasn’t disappointed.
The Tottenham full-back has shown a side of his game never seen before. He started the scoring in Belgium's 3-2 comeback win over Japan in the round of 16.
Vertonghen with his calculated runs and accurate passing has been Belgium's darkhorse. If Belgium is to have any chance of beating Brazil then Jan Vertonghen has to be at his best.
Right back
When Dani Alves retired, Brazil had a huge gap to fill. The Brazilian is often regarded as on the greatest right-backs of all time.
With options looking scarce brazil had sort out this problem if they wanted to challenge for the world title and step up Fagner. The Corinthians right-back has been efficient for the samba nation so far.
If the 29-year-old continues his impressive display then it won't be a surprise if any of the top European clubs come calling for his signature.
