The 22-year-old played 21 league games for the Dons during his loan spell with the club earlier this term, and he will win a league medal if the Dons manage to triumph in the league this season.
"I really enjoyed myself up there and if they win it I get an SPL winner's medal - and that would not be too bad to take home," said Ward.
"The loan spell was something Liverpool and myself felt was needed as I had not played much first-team football coming into this season.
"It went really well and it was a bit bitter-sweet coming back as we were fighting for the league and I was playing week-in week-out.
"Getting called back is a bit of a different challenge than being a number one.
"You have to work harder in training and push the man ahead of you because you want his jersey."
