Oscar's £25million move during the summer brought into the same squad as Lampard, 13 years older than the Brazilian and one of his favourite players.
"I loved to watch him when I was growing up. I always thought he was an outstanding player," Oscar said.
"I know I can't wait to play alongside Frank Lampard but my boyhood idol would have to be Kaka. He plays in the same position as me and he is an exceptional player."
