Manchester United midfielder Shinji Kagawa insists he isn't jealous of his former Borussia Dortmund teammates.

He insists watching Dortmund lose that all-German final against Bayern Munich at Wembley in May just made him more determined.

"I was proud to see my former team play in the Champions League final, and I was very excited for them - but it didn't make me feel I had made the wrong choice," he said.

"In fact it made me feel stronger because I want to be on the same field in future."
