The recovery is being overseen by physiotherapist Rafael Martini who has worked with Neymar since the beginning of his career at Santos and now works with Brazil and PSG.
Neymar has suggested that he is unsettled at Paris Saint-Germain after saying that his time in the French capital has felt "like years".
The 26-year-old attacker is now sidelined with a fractured metatarsal, but was ripping it up for PSG before his injury and was destroying the French league.
Although Casemiro calls the move unlikely, he also admits that Neymar knows he could move to Real Madrid and when they link up at the World Cup this summer, they'll undoubtedly have some discussions about the forward's future.

I've played in numerous positions apart from centre-back and goalkeeper I think. "I think he has to change his football brain", he said.
During his interview with Brazilian media house Esporte Interativo, Neymar said that his first five months in France have been equivalent to five years.
It's mentioned Neymar has suffered an average of 5.2 fouls per game as opposed to the much less demanding average of 3.2 per game he suffered during his four-year tenure in La Liga. "He does insane things".
A move back to Spain will require yet another world record fee as PSG will be unwilling to let one of their prized assets leave the club for less than what they originally paid.
But it is said that the former Barcelona star has reportedly informed Messi of his intentions.
Neymar knows about Real Madrid's interest in him, and holds all the cards to make PSG dance to his tune. I hope he comes this season.
