The Dutchman joined TSG on-loan for the season.
He told Kicker: "I think I had the chance to go to TSG four years ago, but it was not the time to leave Eindhoven."
On Brighton, Locadia added: "I played some games there, then I just sat on the bench for a long time. I had no rhythm, too little match practice.
"I also had other options in other leagues, but Hoffenheim was currently the best for me. Whether I only play here this season, you will see, that is future music."
