Shaw's rise to England international has filled his old friend with pride.
''He is a top player, a top lad and has got all the attributes to be a world-class left-back,'' Ward-Prowse told PA Sport.
''He is on that path and he has just got to keep his feet grounded, make sure he works hard and I am sure he will be there.
''To see him make the journey with me since we were nine years old and then obviously for him to kick on in the last bit is incredible to see.
''I am really gunning for him to go to the World Cup.''
