Liverpool have arrived in the United States to continue their pre-season plans against Borussia Dortmund this weekend.
DC United and former Manchester United player Wayne Rooney has revealed Jurgen Klopp, who guided Liverpool to the Champions League last season, has made just one mistake in his career.
The former England captain told Bild: "
Jurgen is a manager every player would love playing for. You can see how much fun his players have playing under him. I met him once, he is an amazing guy.
"His only mistake is that he works for Liverpool and is successful there. I have much respect for Jurgen Klopp and for what he already has achieved. Not only in Liverpool, but also in Dortmund. This guy really has it. And he has his best years still upon him."
