Shorey had been linked with a season-long loan move to Fratton Park, but decided to stay with Villa.
“The interest from Portsmouth came really late in the window,” Shorey told The News.
“I didn’t have a lot of time to think about it and I decided it wasn’t the right thing for me to do.
“I’d come off the back of a few good wins and I was in the team playing well, I thought. I made that decision and I’m happy with it.
“Portsmouth can say what they want. At the end of the day I didn’t feel it was the right move for me and that’s the bottom line.
“I have no hard feelings, they are nice people down there and I wish them all the best, but I’m a Villa player.”
