The 22-year-old has been out of action since September, when he underwent surgery on his anterior cruciate ligament, and has since relinquished his place to full-back Andre Wisdom.
"It's always good at any club to have competition for places," the Liverpool Echo quotes Kelly as saying. "Whether you are looking to take someone's place, or you are looking behind at someone who is pushing for yours, it's always a great thing to have.

Kelly recently penned a fresh long-term contract at Anfield.
