Bellingham paid tribute to Ancelotti as he received his Golden Boy Trophy today.
He said, "I put my efforts and a fierce commitment to excel with work, but the credit goes to Mr. Ancelotti who found the right position for me and gave me more freedom on the field.
"So now I fly on the field thanks to him.
"I know I am disappointing him in one respect ... I still don't speak Spanish. Sorry, but I am encountering unexpected obstacles with this language. It is difficult for me, I admit it. In any case, I promise the maximum commitment, guaranteed."
On future winners of the award, Bellingham said: "I will say three names for the future. First of all, Arda Güler, is a phenomenon, we see him training and we are delighted with him.
"Then my former teammate Jamie Bynoe-Gittens from Borussia Dortmund. And finally, my brother Jobe, a thoroughbred striker like our father. By the way, I send a greeting to my friend Jamal Musiala, who came second, and with whom I shared the dressing room of the English youth teams for about three years."
