Kelly has been out of action since last September after rupturing a knee ligament against Manchester United at Anfield, but has since returned to full training during the current pre-season programme.
And now the 23-year-old has set his sights on adding to his solitary senior England cap ahead of next year’s tournament in Brazil, but knows he must regain a place in Brendan Rodgers' starting XI first.

"But for me at the start of the season I just need to concentrate on doing well for Liverpool. I need to show why Brendan Rodgers gave me the new contract. I need to give Brendan and Liverpool something back and show why he has faith in me.
"My first target is to get my fitness up, crack on and get back to where I was at the start of last season.
"In football, things can change quickly. If I take my chance again and do well then I'm sure the England manager will be watching."
Kelly also admitted that he has already been impressed by Liverpool's two summer Spanish signings, Iago Aspas and Luis Alberto, from Celta Vigo and Sevilla.
"They are new to me but I've seen in training already what they can do," he added.
"They have both got really quick feet and now it's just a case of them settling into English culture. I'm sure they'll be hitting the gym, that's what most foreign players seem to have to do when they come over here as the Premier League is more physical than other leagues.
"They seem like great lads and really talented players."
