"I am happy first of all. [I am] excited, I feel blessed and, like I said, I am really happy to be here," Sanderson, who has spent two previous loan spells at St Andrew's, told the club's official website.
"It has been an ongoing thing for quite a while now, so I am happy that we have got it over the line and now I'm home."
