Shinji was asked for his opinion on former team Borussia Dortmund’s run to the Champions League final in 2011/12.
"I felt very proud to see Dortmund in the final and I was excited," he said. "I was proud of my former team-mates. I spent more than two years there.
"I don't feel like I made the wrong choice. Of course I wanted to be on that pitch but it just made me feel very strongly about wanting to play in a similar match in the future."
