Cole, who spent three years with the MLS club, is undertaking his coaching badges whilst working with the Blues' U14s and U15s side.
"I've been speaking to Neil Bath about my future for a couple of years now and originally my interest leaned more towards scouting," Cole told the club's website.
"I enjoyed watching games and analysing players or team units like defence and midfield but it was when I was playing in Los Angeles [for LA Galaxy] that they gave me a bigger role with the coaching side.
"I wasn't just a player there, I was sitting in on the video analysis sessions and doing one-on-one coaching with some of the younger players, which I really enjoyed.
"I liked to see the benefits of telling the players something and watching them produce it in game situations – that was something I loved to see so that then led to a different conversation with Neil to tell him I wanted to be a coach."
