The pacey winger left the Reds on the best note in 2016, winning the A-League double and being crowned the club's player of the year.
That fine form saw Goodwin secure a move to Europe and be regularly included in Socceroos squads under Ange Postecoglou.
Restricted mainly to the bench however, the 26-year-old still only has three national caps to his name and after a frustrating season in Netherlands couldn't force his way into Australia's World Cup side.
Back in the A-League, a return to the Socceroos is firmly in Goodwin's sights and it played a big part in his decision to return to Adelaide.
"I think when I left Holland the end of it didn't end as I would've liked," Goodwin said speaking to Adelaide United.
"But obviously looking for a new opportunity to really take me to the next level and put myself back in the face of the Socceroos. I guess the Asian Cup is my main target for that.
"But I felt that the best thing for me was to come back to Adelaide United and really spring board from there."
Despite a strong first season with Sparta, Goodwin found his chances to impress limited in their most recent campaign as he earned just eight starts.
Though ending on a frustrating note, the Adelaide junior savoured testing himself overseas and feels he returns to the Reds a better player.
"You really learn a lot form European football both on and off the field, and for me I guess I've grown a bit as a player," he said.
"Being in relegation battles really improves your composure and calmness."
