Lazio striker Ciro Immobile is grateful to have played under Jurgen Klopp at Borussia Dortmund, describing the German coach as "someone you do not forget".
Immobile was brought to Dortmund by Klopp in 2014 as a replacement for Robert Lewandowski but scored just 10 goals in 34 games before heading to Sevilla the following year.
He again struggled in front of goal at Sevilla but has since revived his career at the Stadio Olimpico, scoring a combined 103 goals in the last four Serie A campaigns.
