Neymar has been recuperating in his homeland after an operation on a broken metatarsal in his right foot, following an injury back in February which has left him sporting a protective boot.
Despite his club season being over, thanks to the injury and PSG being dropped from the Champions League, the Brazilian star will be racing against time in order to be pass his fitness test for the World Cup.
During the recovery period, Neymar has been linked to a move to Real Madrid from the Ligue 1 leaders. The rumours are flying less than a year after the 26-year-old joined the Paris squad for a record-breaking £198million.
PSG chairman CEO, Nasser Al-Khelaifi, is convinced that Neymar will remain with the French club.
