Dragan, who is making a name for himself at the Serie A club, spoke highly of the 27-year-old Nigerian international, describing him as someone who "radiates kindness" behind the scenes.
The young talent believes Lookman's guidance has been instrumental in his growth, both as a player and as a professional.
Lookman, widely regarded as one of the best African talents in European football, has been in outstanding form for Atalanta.
His performances have not gone unnoticed, with multiple Premier League clubs reportedly keeping a close eye on him ahead of a potential move.
"There are three people - de Ketelaere, Lookman, and Retegui. That's top level!" Dragan said in an interview with Dynamo Kiev, as per Brila.
"Lookman. As a person, he is very pleasant, friendly, cheerful, always with a smile on his face. Ademola radiates kindness."
