The midfielder's girlfriend gave birth to their first child, Elexa, six weeks ago and he insists he's relishing the responsibilities that come with being a father.
Now he's hoping to show how much he's grown since joining Liverpool from Sunderland two years ago over the course of the new campaign.
Henderson explained: "It was the best day of my life when she was born and I have enjoyed every minute of being a dad.
"My girlfriend has been brilliant in terms of doing the feeds during the night. It's meant I have still been able to get my sleep and been fresh for training.
"It's another step for me in terms of growing up. Over the past three or four years in the Premier League, first at Sunderland and then my first couple of years here, I feel like I've learnt a lot.
"I have put a lot of work and effort in and now it's my time to go and show people what I'm all about. I feel I am ready now.
