The former Tottenham Hotspur midfielder, has been linked with a switch to Serie A for some time, has only just become available after visa problems.
Chris Ramsey was recently quoted as saying by BBC Sport as saying, though he was happy for the 26-year-old to be available again after his visa problems caused him to miss the end of last season and the beginning of this one, Sandro would have to fight to reclaim as place in the starting lineup, with central midfield heavily reinforced this summer by the R's.
With Sandro, who made 17 appearances last season, also certain to be on big wages at Loftus Road, and Milan committed to investing to improve recent fortunes at the famous club, there are certainly reasons why a move would be attractive to all parties.
The defensive midfielder shone during Spurs' matches against the Italians in their 2010-11 Champions League campaign.
However, though the English transfer window runs to 6pm tomorrow, the Italian window ends tonight, meaning that if a deal was to be completed it would have to happen in the next few hours.
Considering problems Sandro has had in relation to injuries in revet seasons, it will be a stretch for the Brazilian international to make it across to Milan and complete a medical before the Serie A deadline passes.
