The Brazilian international has had a difficult time at Loftus Road since arriving from Tottenham last summer.
The defensive midfielder was bought from London rivals Tottenham for what the BBC say was a figure of £10 million last summer, but only featured in 17 games for the Hoops after a knee injury in the middle of the season, before problems with his work permit meant he wasn't selected for the club's last three games that saw relegation back to the Championship.
Sandro has also missed the start of this season as he has attempted to put together clearance to return to football, and he is once more available to Ramsey.
However, the former Spurs coach has insisted it won't be a case of the 26-year-old walking straight back into the team, with the R's having strengthened central midfield this summer.
"He won't come straight back into the team. Once you create that competition, I think the standards will go up even more."
QPR have made a decent start this season in the Championship, losing their first match but winning their last two to take them into the playoffs - a position that must surely be their minimum target for the season.
But Sandro's return, even if it is gradual, is sure to be a boost to Ramsey and everyone at Loftus Road, considering his experience of international football and Champions League.
