Doubts over Neymar's debut at the World Cup were dissipated on Tuesday as the former Barcelona and Paris Saint-Germain star was back to training after the Brazil forward had undergone new tests on his injured right leg on Monday. The 34-year-old Neymar, in his fourth World Cup, has been sidelined since getting injured with Santos in Brazil on May 17th. Brazilian media said Brazil's medical staff was hoping to have him back fully fit for the knockout stages, but now it looks like his return could be anticipated.
