#1 Neymar
Who else could be on top of this list? Neymar is one of the best in the world and he has shown it to everyone already. Although he had a terrible game against Switzerland, he will still be the biggest threat to any opposition he plays against. He was fouled 10 times in the game against the Swiss and hardly had possession of the ball.
He will look to bounce back and deliver a match-winning performance for Brazil against Costa Rica. He is perfect at almost everything and will look to deliver the good this time around.
The world's most expensive player will look to add to his tally of 55 goals from 86 matches. Neymar is, without a doubt, the best player who will feature on matchday 9 and will surely look to grab the spotlight.
