Liverpool manager Jurgen Klopp says Mario Gotze is the greatest player he has managed.

The German gave Gotze his debut at Borussia Dortmund, and managed him over the following four years before Gotze moved to Bayern Munich.

"Mario Gotze was unbelievable," said Klopp, who quit Dortmund in 2015, to Soccer Laduma. "I keep in contact with a lot of my Dortmund players.

"What do I miss at Dortmund? Everything! It was a fantastic time, but it was the right time to leave. I don't want to go back unless we play them."
