The Reds have moved up to sixth on the Premier League table with some inspired performances in the second half of the season and Shelvey says it has been the influence of the famous Scot which has put them back in place for Europa League qualification.
"In January, when the boss took over, you would not have expected us to be fifth come the end of the season," the youngster said.
"We were struggling, even though the training was good and Roy (Hodgson) was a good manager.
"I just think Kenny has got everyone going and you can tell around the place there is a massive team spirit and it is showing in our performances.
"He has got us passing and moving, which Liverpool fans want to see, and I think it is good because he has given a lot of youngsters a chance as well."
And Shelvey added that he was looking for a big future at Anfield with the help of some of the clubs big guns.
"He has said that I am in his plans. I have got a lot to look forward to," he added.
