The 19-year old Australian forward signed a three-year deal with German club Borussia Monchengladbach on the weekend but will head straight to the Bundesliga outfit and will not remain on loan with the Roar for the rest of the 2013/14 A-League campaign.
"The club in Germany has made the call and they want him there now," said Mulvey.
"They wanted him for the final half of this season, and I'm not going to argue with them about what's good for Kwame. They've been scouting him for a few weeks and they know a talent when they see one."
