"I will always be a Liverpool fan," Spearing told Sky Sports News Radio. "A lot of dreams came true, but now in football terms it was time for me to move on and get regular football. Regular football for me is the main thing for me now.
"Last year's loan was a massive part of my decision. I really enjoyed my time there, the lads, the backroom staff and everything about the club was something I really enjoyed and, as soon as I knew the manager was interested again, it was a good and easy decision to make."
Spearing made 55 appearances for the Reds during his Liverpool career.
