Chelsea have completed the signing of Barcelona right-back Juliano Belletti for an undisclosed fee.
Belletti scored his first goal for Barca in the Champions League
The 31-year-old Brazilian has put pen to paper on a three-year deal after agreeing personal terms and completing a medical at Stamford Bridge.
Belletti told Chelsea's website: "We reached an agreement and so did Chelsea and Barca. Everyone is happy."
Chelsea are believed to have turned to Belletti after their attempts to sign Sevilla's Dani Alves stalled.
The Spanish club turned down two improved offers for the full-back this week, with Chelsea and Real Madrid both in the hunt.
The Spanish club were understood to want £27m for Alves but Chelsea chairman Bruce Buck said the club would not be forced into spending above the market price.
Belletti joined Barcelona in 2004 from Villarreal but only made 13 appearances for the Catalan club last season.
The Brazilian scored the winning goal in Barcelona's Champions League win over Arsenal in 2006.
However, the arrival of World Cup winner Gianluca Zambrotta squeezed Belletti out of the Barca first team.
"It has all been a great surprise. I only spoke about the move on Wednesday.
"I know a bit about what the Premier League is like," added Belletti. "I know it's a tough league but I'm coming here with plenty of ambition and desire. I want to win trophies.
"I am a typical Brazilian full-back. I like to get forward up the wing."
Buck admitted they had been put off several players because of their asking price.
He told 5live: "When we are buying players there is no doubt about it there is one price for Chelsea and one price for everyone else.
"We have to do our best to fight that.
"If the price of the player being requested is inappropriate then we will walk away. There are a number of transactions that we walked away from for just that very reason.
"In the first summer, in retrospect, some of the players did not turn out to be as excellent a player as we thought they were but that is also part of football.
"That happens to every club - that not every purchase works out. We are trying to be a little more careful going forward."
