Arnold was interviewed by the media and talked about his feelings about joining Real Madrid.

"Conversation with Bellingham? As a friend, we talked about his experience here. When you change teams, you want to know about the new team. He told me he loved it, and it was reflected in his game, and he enjoyed his football. Everything told me that this was the right choice for my career development."

"I am so happy to be here to come to Real Madrid, this is a place for dreams to come true. It was a very exciting time for me. I can't wait to start a new chapter here. It was an amazing achievement to be here, but there is still a lot of work waiting for me."
