The striker has scored once in eight appearances for the Owls since joining in November and has not played a first-team game for Stoke since August 2010 due to injury.
His initial spell at Hillsborough expires in a week's time and the 33-year-old is simply determined to play football following a torrid time with injuries.
"Of course, I need to play; I have been working hard to get back my fitness and also get back in the squad at Stoke," said Sidibe in the Sheffield Star.
"If I can't be in the squad there, I need to play; I have been out too long to sit watching games.
"All the work I have done has been to get back in the squad at Stoke, but if there is no room for me there, I need to play.
"I don't know what is going to happen. I am here on loan and am doing my best. The future is not in my hands really.
"The only thing I can do is to play and give my best for Sheffield Wednesday while I am here."
