Ciro Immobile has described Jurgen Klopp as "someone you do not forget” despite only playing under the German for one season.
The forward was brought to Borussia Dortmund by the current Liverpool boss in 2014 as a replacement for Robert Lewandowski, who left to join Bayern Munich.
Despite arriving in Germany with a rich reputation, Immobile only managed to score 10 goals in 34 games before heading to Sevilla the following year.
But that hasn’t stopped the current Lazio striker, who struck 36 goals in 37 Serie A games last season, from lavishing praise on Klopp, who he believes is someone you give you all for.
"Klopp leaves something behind for you. You don't forget someone like him," he told Sport Bild.
"I was lucky to be able to play under him. He's a super emotional trainer. Someone for whom you fight for every ball.
"He demands that of you too, and you can see that in his behaviour on the sidelines."
While the forward also revealed why he struggled to make an impact at Dortmund.
He said: "I think that I just moved to Dortmund at an inconvenient time as far as the team was concerned.
"With Klopp, BVB became champions in 2011 and 2012 and then came second twice. After the first half of my season there, we were second from last in the Bundesliga.
"That meant young, foreign players being left out. I don't think Klopp didn't see any quality in me, but in this difficult phase he put more trust in players he already knew and could rely on."
