The 27-year-old has been on loan with the Blues from Derby County since January, having struggled for many opportunities at the iPro Stadium.
And while he has found it similarly difficult to hold down a place for the Blues - with his appearance against Reading at the weekend being his first in over a month - he insisted that he hopes to convince Gary Rowett to make his switch permanent.
"That's what I am here for," he told the Mail. "I have got to fight for anything that happens in the summer.
"I have got one year left at Derby, I am not going to come out and say 'I want to stay at Derby and fight for my place and this and that'.
"I am here at Birmingham, I am trying to impress the manager and that’s what it’s about."
Although Shotton had previously struggled to make an impact during the first few weeks of his loan spell, he did an excellent job of proving what he can do against the Royals.
Not only did he help Birmingham keep a clean sheet at the Madejski Stadium, but the former Stoke defender was also able to get onto the scoresheet, doubling the away side's lead just before the half-hour mark.
And while Rowett's hesitancy to select him regularly may have been down to the fact that he is seemingly more of a utility option who is capable of filling in anywhere across the back line, the way he played alongside Michael Morrison in the centre may convince the manager to not only give him further opportunities, but also to make him one of his main targets for the summer.
