The 22-year-old had a difficult first campaign at Anfield last season but believes he has learned from the experience.
"I think there were a lot of positives to be taken out of my first full season," he said.
"Admittedly there were also a lot of ups and downs but I learnt a lot and I became a man in that time.
"I've just got to use all the experience that I gained in that year and hopefully this can be a better year for me.
"Obviously all of us players are disappointed if we haven't played very well or we've got beat but you've just got to go away and stay positive and keep training hard, keep working hard and eventually it will come right for you.
"I look to kick on every season. This season is no different.
"I just need to work hard and try and get into the team first. I need to make sure I train well and that come the weekend, the manager can't leave me out."
A summer stint with England at the European Championship, where he made two substitute appearances has also helped his confidence.
"Being there with these types of players gives you more confidence when you go and play at the highest level," he added.
"It gave me a lot of confidence, so let's hope I can use that and just keep pushing forward."
