United manager Sir Alex Ferguson says Keane could make it at Old Trafford.
Keane told MUTV: "I was surprised but really pleased to win the award. It's great to know that it's been voted for by the fans, because they come to watch us and follow us throughout the season."
Looking back on his senior debut this season, away to Aldershot, the award-winner said: "It was incredible. Just to travel with the first team is special. But to get on the pitch is unbelievable. It's something I and my family had dreamed of.
"Now I hope to go on the pre-season tour with the first team and if that goes well, then I might go on loan or stay here. It will be up to Sir Alex of course."
