Wayne Rooney was full of praise when asked to rate Liverpool boss Jurgen Klopp.
Klopp won his first title with Liverpool last season, capping off the Reds meteoric rise over three seasons with a Champions League medal.
Formerly of Manchester United and Everton, Rooney admits the only shame about Klopp's talents is they are being used at Anfield.
"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," Rooney told Sport Bild.
"His only mistake is that he works for LFC 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."
