Carragher will hang up the boots at the end of this campaign.
"Looking at the season I think if you remember the start it was difficult with the transfer window situation," said Carragher, referring to Andy Carroll's loan to West Ham and a failed bid for Clint Dempsey, which left Liverpool with only one senior striker in Luis Suarez.
"From the start we had a lot of young lads in there and it wasn't easy.
"The second half of the season there has been more experience and the manager has implemented his ideas more and you can see that in results in and around January-February time we went on a decent run.
"The manager made a couple of signings (striker Daniel Sturridge and midfielder Philippe Coutinho) in January which gave us a boost so we're showing positive signs but we have to take it into next season."
