Iain Turner is on a mission to show what he can do every time he gets an opportunity in a Blades shirt.
The Scottish goalkeeper was a late addition to the starting line-up in Tuesday evening's victory over Colchester United, called up from the bench at the 11th hour after Mark Howard sustained a back problem in the pre-match warm-up.
"Mark was expected to play but halfway through the warm-up he went in for treatment," said Iain. "At that point I didn't know if I was going to play but five minutes later one of the staff came out with the news, so I continued with my preparations, ready for the game.
"Simply, you have to be ready, that's my mentality, whether I'm warming up to be on the bench or to play. Obviously, if you are playing regularly you are a little sharper but I was pleased I was able to make a save in the first minute and another from Chris Porter in the first half."
Turner, who has now played four senior games for the Blades, including the 2-0 Sky Bet League One success over Swindon Town last month, added: "When I signed I knew I would be number two and had my work cut out to get a game because Mark (Howard) is a very good goalkeeper.
"But when I get the chance I like to show what we can do. I don't know if Mark will be back for the weekend but if not I'll prepare right and make sure that I'm there and ready when needed."
