The Brazil international moved to United from Ajax in the summer and might not have played alongside Ronaldo at all, with the veteran forward linked with a move in order to play Champions League football.
But he is happy at experiencing life alongside the five-time Champions League winner and is looking to learn as much as he can.
"I'm feeling very happy, and I told this to him, because we always follow up and have this dialogue," Antony told ESPN Brasil. "He always makes me feel comfortable. It looks like I have known him for a long time, and I told him this.
"He has a beautiful history and he is a huge reference for those who are younger than him. Something flashes in my mind, like we play videogames [of him], watch him on television and right now I share some moments with him, for me it is very rewarding.
"Like I said: I'm still young, I am 22 years old and I'm learning a lot from him."
