Melbourne City defender Ben Garuccio has joined A-League champions, Adelaide United.

Garuccio, originally from South Australia, has signed a two-year deal.

The 21-year-old, who has spent the past four years at City making 45 appearances, said he is thrilled to be back home home in Adelaide.

"To be back in Adelaide and to be playing for the team that I supported when I was a little kid is very exciting for me.

"With football you never really know where you're going to end up and it's not as if you can really pick and choose where you'll play. But to have signed with United is a great feeling.

"The team had an incredible season last season and had some really tough matches against Melbourne City so I know how much talent is in the squad.

"The season is still a while away and there's a long pre-season to go through, but I can't wait to get out there and get back to playing and training hard. "
