Chelsea completed a huge day of business on Monday by signing Benfica defender David Luiz.
The Blues are believed to have agreed a £21m fee with their Portuguese counterparts to end their lengthy pursuit of the 23-year-old Brazilian, with Serbia midfielder Nemanja Matic heading in the opposite direction as part of the deal
And Luiz, who has agreed a five-and-a-half year contract with the Premier League champions, told their official website: “I am delighted to be joining a big English club, and I know very well the quality that Chelsea has.
“It is a major challenge for me but I am determined and confident in my ability to adapt to this excellent league, and I look forward to meeting my new-team mates.”
Chairman Bruce Buck added: “It is a delight to have completed this transfer for a fantastic young footballer who we have admired for some time.
“David has played in the Champions League and the squad now has a more experienced look to it that will hopefully serve us well for the rest of this season and going forward.”
The Blues had earlier wrapped up a move for Liverpool and Spain star Fernando Torres after reportedly agreeing to pay around £50m for the World Cup-winning striker.
