Borussia Dortmund star Pierre-Emerick Aubameyang has heaped praise on former manager Jurgen Klopp.
Aubameyang has garnered interest from some of Europe's top clubs including Arsenal, Real Madrid and Paris Saint-Germain after scoring 33 goals in all competitions this season.
The 26-year-old believes current Liverpool boss Klopp played a key role in his rise to prominence during their time spent together at Dortmund.
"Klopp brought me a lot," Aubameyang told France Football.
"He gave me strength of character and made me develop defensively. The two years I spent with him were very useful to help me step up a level. He's someone charismatic and I have a lot of respect for this man.
"He often asked me to go and discuss things with him -- when things weren't going as well but also when they were going well.
"It's good to have a coach who speaks to you, who gives his opinion and knows how to advise you.
"He's one of the three managers who gave me the chance to become who I am today along with [St Etienne's] Christophe Galtier and Thomas Tuchel, who's also in the process of making me reach another milestone."
