Youssoufa Moukoko has thanked Lukasz Piszczek, Emre Can and Julian Brandt for helping to ease his transition into the Borussia Dortmund senior squad.
The 15-year-old forward, who boasts an incredible record of 183 goals in 120 games for Dortmund's youth team, is working with Lucien Favre's first-team group as they prepare for the 2020-21 Bundesliga season.
Regulations in Germany's top flight mean Moukoko will not be able to make his competitive debut until he turns 16 on November 20, but he will be getting up to speed during the intervening period.
"Lukasz Piszczek helped me a lot, but Emre Can and Julian Brandt also support me," he told Bild.
On 35-year-old full-back Piszczek, Moukoko added: "He pulled me straight to the side and said, 'Just have fun, be yourself and don't be afraid with us professionals'."
In the meantime, Moukoko still has ambitions in the youth categories.
"I will use the time until November in the under-19s," he said. "I still want to break the 200-goal mark."
Giovanni Reyna, 17, was a breakthrough teenage star for Dortmund last season.
The son of former USA international Claudio Reyna, the youngster has paid tribute to the role of his late brother Jack in his formative years as a footballer.
Jack died of cancer aged 13 when Giovanni was nine.
"It was Jack who got me excited about football," he told SportBild.
"People always think that I became a footballer because my dad, Claudio, was already a professional.
"But it was my late brother who sparked my passion for football. Without Jack I wouldn't be at BVB today."
