Finishing his two week coaching tenure with the Roar, Kluivert put the players through a series of drills at training before saying his final goodbye to the squad.
"If you have to say goodbye it is always a bad feeling," he said.
"Working with a young squad which has a lot of talent is always nice.
"I learnt a lot about coaching through how Ange (Postecoglou) is working ... he and I had very good time together.
"(So) it is always difficult to say goodbye and I wish the boys all the best."
Holland's all time leading goal scorer was a massive hit at the club, with the squad - especially the forwards - working overtime to learn as much as they could in the little time they had.
And despite the Roar's gruelling season falling short of a final's campaign, Kluivert left predicting the club would make a swift return to the Hyundai A-league summit.
"They have a lot of talent in this group ... some of them have a really bright future," Kluivert said.
"It was fun working with the boys and I hope for next year they can do better."
