Liverpool Echo says, Stewart returned to Anfield from a loan spell at Swindon Town in January, but only featured in four Premier League games for the Reds due to an ankle injury.
However, the 23-year-old is determined to establish himself at Liverpool next season, after three loan spells at Cheltenham Town, Burton Albion, and Swindon.
“Trying to break through, trying to stay fit and trying to be ready for when I’m called upon is my aim,” he told the club's official website.
“Next season there are going to be a lot of games, especially if we qualify for the Champions League, so I just want to keep fit in the summer, work hard and then see where the season takes us.
“That’s the thing that keeps me going, I have done it before, so I know it’s possible. I see the players I train with and they’re amazing players I’m competing with and playing with, but I will keep believing because I’ve been through it before.”
