The anchorman has been out since January with a knee injury but is aiming to come back stronger next term, and has urged his team to qualify for the Champions League
The Brazilian has been out since damaging the anterior cruciate ligament and meniscus in his right knee during a goalless draw with QPR at Loftus Road in January, ending his season.
Sandro revealed the injury was particularly difficult to take as he felt he was in the form of his life, but will be stronger upon his return, and wants to play for his country again.
The 24-year old told Globo Esporte: "I've got three months to go. I've started to run, I'm developing.
“Sometimes I try too much and the knee swells up. I have to listen to the doctor. I have to give the injury enough time, but I dream that I am playing.
"I was in the best phase of my life as a player, so it was hard when I had the injury.
"Hopefully I'll be back playing with my club and then I can think about the national team. When I return I will be stronger."
The Brazilian has also urged his team mates to fight for a Champions League spot at the end of the season, claiming the competition is a step up from the Europa League, and has fond memories of Europe’s top competition.
Sandro continued: "We have to fight to stay in fourth place. Last year was complicated. We did not classify because Chelsea were the champions of Europe.
"The Champions League is a different competition [to the Europa League]. Everything the fans see is what the player feels... the entrance music, the stadia, the fans... everything is amazing.
"I made my first appearance in the competition in 2010 when we beat AC Milan at the San Siro. We beat Inter Milan, too, and we only lost in the quarter-finals to Real Madrid.
"It was a really great experience. Hopefully the club will compete in the competition again."
