Liverpool manager Jurgen Klopp has picked out Robert Lewandowski as the best player he has ever managed.
The Bayern Munich marksman worked under Klopp during their time together at Borussia Dortmund, winning back-to-back Bundesliga titles in 2010-11 and 2011-12.
During an interview with Bild, the German praised the polish striker, who has been impressive for Bayern Munich in the last three seasons.
"Robert Lewandowski. It actually won't be fair to say that about any other player except Lewy," he said.
"What he has made out of his potential, how he pushed himself to become the player he is today, that's extraordinary."
He went on to highlight more what makes the current Bayern number nine stand out from the many players he has managed.
"Lewy took every step he needed to take to be that goal machine. Everyone," he added.
"He has immersed himself in the game, he just knows in every situation what he has to do, where he has to go. Lewy is an absolute machine."
Klopp signed Lewandowski from Lech Poznan in 2010 as a promising 21-year-old, but he has delivered at the highest level, particularly starring for Bayern as they won a sextuple last season.
