Ferreira told the Evening Standard: "I wanted to go with the coach, who I know well.
"It will be really good because I will be going to a league which I like and I also will be able to provide a better life for my family. I knew a few days ago that it was settled with Chelsea and I was really pleased."
With Mario Melchiot out of contract and on his way out of the club, Glen Johnson will be competing with Ferreira for the right back slot. Together, they will have cost almost £20 million!
