The powerful midfielder has spent most of his professional career playing in the top flight in Brazil and England, but he was not snapped up when QPR were relegated last season.
Instead Sandro has, rather surprisingly, remained at Loftus Road - where he still has 18 months left on his contract.
The 26-year-old has made 11 appearances for Rangers to date this term, but he has not ruled out a move in the January transfer window.
“I have a contract here for one-and-a-half more years,” he said.
“My focus is here and hopefully the Premier League next year.
“If Brazil want me, they’re going to ask, but I agree it’s difficult for me in the Championship. This is not in my head.
“There are too many games here; it’s hard, but we are paid for it.”
The gruelling schedule of the Championship means Sandro has had to be carefully managed so far this season by QPR.
Although he is undeniably one of the most talented players in the whole of England’s second tier, his injury record means that Rangers have had to deploy him with caution.
QPR have been keen not to over play Sandro, in the risk of him picking up any further injury problems.
QPR are currently in 15th place in the Championship table, 10 points away from the play off spaces.
