Man Utd, Barcelona target Hummels preparing for Borussia Dortmund exit
"One day, I will say that I am keen on a move. Playing in a new country would be flattering. I have already had offers, which were interesting, but I told myself it wasn't the right time to leave," said Hummels.
"There was a reason behind that, as I had extended my contract recently. When a Borussia Dortmund player moves it is not to any club. In the Bundesliga, it would just be about Bayern Munich. In Europe, there are only about four or five clubs that would really interest me."
