Philippe Coutinho is not anxious about Neymar after the Brazil star limped out of training with an ankle problem in Sochi on Tuesday.
Brazil have been handed a huge disappointment after Neymar was taken out of their training session after just ten minutes. I have goals and I focus on them, I have new challenges all the time, and this year's World Cup is one of them, like also not getting hurt or making the transition from club football to worldwide football. The 26-year-old started to limp in the first half but said after the game he was not injured.
However, Coutinho insists Neymar remains the key figure in Brazil's pursuit of World Cup glory.

Brazil may have struggled in their World Cup opener but their failure to beat Switzerland has not left the players worrying about qualifying for the knockout phase just yet, midfielder Philippe Coutinho said on Tuesday.
A middle aged man is crying foul following Brazil's dramatic draw against minnows Switzerland as Russia's World Cup tournament entered its forth day on Sunday.
In the wake of the match, Neymar urged the referees to "do their jobs" after an incident-filled evening at the Rostov Arena, while the Brazilian faced further backlash for his underwhelming performance against the Swiss by a number of the Brazilian press.
In a news conference on the eve of Sunday's match, Brazil coach Tite said Neymar is still not 100% fit as he recovers from surgery to fix a broken bone in his right foot.
"There is a lot of pressure when we play because the world of football is looking at us", Tite said Saturday.
Mexico though only lost one game in qualifying and have always qualified for at least the second round of every World Cup they have played.
