The 25-year-old joined the Blades towards the latter stages of the Premiership campaign. Kilgallon has mounted two promotion challenges with the Blades and one survival quest - all ended unsuccessful.
Speaking on his future, he confirms that he hasn't been offered a new contract by the Bramall Lane club, something which does worry Blades fans. He told Sky Sports:
"I haven't been offered a new contract at Sheffield, I have had nothing in front of me.
"I don't know what's going to happen there, but I have to try and forget about that side and play football.
"I'm 25 now and everyone wants to play in the Premiership. I think it will suit me more to how I play. It's about reading the game and a bit more about time on the ball, whereas in the Championship it's a bit more in the air. But it's all good fun.
"It is an important time in my career and I want to play as high as I can. So if I play well that's what could happen."
