Rodgers oversaw the re-signing of Shelvey.
"I think he's great. With all the passing drills he's doing, he's encouraging us to play all the time which is nice for a football player. Instead of doing a lot of long-distance running and things like that in pre-season, everything has been with a ball, which is more enjoyable. Everyone is enjoying training and looking forward to coming in.
"I think going away (on loan) to Blackpool helped me a lot. It gave me some experience, I scored some goals and I came back a better player. Kenny (Dalglish) gave me a chance towards the latter stages of the season and I thought I showed what I can do."
