The 26-year-old midfielder replaced Anfield legend Steven Gerrard as skipper last summer but was restricted to just 26 matches total due to foot injuries.
Henderson is back to full fitness now, having already notched four appearances for the Reds this term, and admits he is feeling free to change the public perception of him following a tough debut campaign as the Merseyside club's skipper.
"Last year was up and down," said Henderson.
"I was playing games when I wasn't 100 per cent and mentally that isn't great. Mentally I am in a different place and I think you can see that in performances.
"People will look at last season and question whether I should have played at all with my injuries, but that is just the way I am.
"I still don't think he has seen the best of me yet. I have confidence in myself to come back stronger and prove people wrong again."
