"Since I was first able to kick a football, all I've wanted to do to is play for Liverpool," Kelly told BBC Radio Merseyside.
"I need to keep pushing and progressing now I've got the contract. The hard work starts now to try to make a name for myself in the team."
"I've been at Liverpool since I was seven, and the feeling I'm getting playing for Liverpool and getting the chances I'm getting - I don't want it to stop."
"We didn't need that at this time of the year," he said. "Jamie is our best defender and he's the one who brings our team forward and he tells everyone on the pitch what they're doing and he's going to be a massive loss.
"If the boss needs me to fill in any position along the back four then hopefully I can do that.
"I've got to take the chances I get and just hope Jamie gets back as soon as possible as we'll miss him."
