Raphinha joined Barcelona this summer on a five-year contract.
The Blues were one of the leading candidates to land the Brazil international this summer and could have helped played Champions League football.
They even accepted a bid for the talented winger but the former Leeds man had his eyes on a Barcelona move.
Raphinha told La Vanguardia: “Rejecting an offer from Chelsea? Yes, because my dream was to wear the Barca shirt.
“I followed them since I was young, since Ronaldinho arrived. I wanted to be a part of it. The desire was stronger than any other proposal, no matter how powerful it was financially.
“I knew that I might have some difficulties to come and to be registered. But I was also aware of the effort the club was making.
“So I decided to trust and adapt to the economic conditions that existed.
“I was born in La Restinga, a very poor neighbourhood in Porto Alegre. I had a very poor childhood, so to speak.
“But my family taught me that humility and values are much more important than material things and that has saved me on many occasions.”
