Neymar left the Rostov Arena limping but told media that there was nothing to worry about, and his appearance in training appeared to allay any fears that he had suffered yet another heartbreaking injury at a World Cup following his 2014 anguish.
The federation says Neymar has been in pain since the team's 1-1 draw against Switzerland, when he was consistently fouled.

Brazil were not just unhappy with the treatment meted out to Neymar, but also Switzerland's equaliser when the Video Assistant Referee (VAR) system failed to rule out Steven Zuber's equaliser for a slight push on Miranda.

Whether Neymar will feature in those games remains to be seen.
Costa Rica lost their first match against Serbia, ending a five-game unbeaten run at the World Cup finals - they haven't lost back-to-back World Cup games since June 2006, when they lost four in a row. In 1998, Alan Shearer was fouled a whopping 10 times in England's curtain-jerker against Tunisia. We can have one player being the protagonist in one game, then another in the next one, but the most important thing is the group. "When he is on the field he helps us a lot".
