Queens Park Rangers manager Harry Redknapp has admitted that the fitness of some of his players is a concern following the 2-0 defeat to West Ham United on Sunday.
Another defeat left QPR bottom of the Premier League seven games into the season, and Redknapp singled out Sandro as one of the players whose condition is a worry.
"We need to get them fitter," the QPR boss told reporters. "I've put a lot of faith into Sandro, but unfortunately he's had an injury and we need to get him fit.
"When he's fit he's a fantastic player. I had him at Tottenham, he's an excellent player but, at the moment, he's short of fitness.
"The doctor came to me at half time and told me he can only play another 15 minutes. I need players who can play 90 minutes. They've had injuries and missed training. We need to get everyone fit and ready to go."
QPR return to action against Liverpool on October 19.
