In total the teenager made 11 league substitute appearances and he is desperate to prove himself next season.
"I am only 18 but I'm not content sitting on the bench," Ward-Prowse told BBC Radio Solent.
"I don't think I've proved myself," he added. "I only would have proved myself when I'm playing week in, week out.
"Sitting on the bench is not what I'm about. I think I've got so much more to offer the team and the club and it's a horrible feeling having to sit on the bench and watch the likes of Luke (Shaw) doing well because you want to be out there contributing as well.
"The pressure is even greater this year. I'm 18 now, I'm no longer the young pup of the team when I was coming through.
"Now I'm almost established and I need to make that next step and challenge Jack (Cork) and Morgan (Schneiderlin) for a place in the team and hopefully establish myself in the side as I did at the start of last season."
