David Luiz is set to move from Chelsea to Paris St Germain after the clubs confirmed a deal had been agreed for the transfer of the Brazil defender.
Luiz will move for £50million, a world record fee for a defender.
A statement on chelseafc.com read: "Chelsea Football Club and Paris Saint Germain have agreed terms for the transfer of David Luiz to the French club.
"The move is now subject to David Luiz agreeing personal terms with PSG and passing a medical examination."
Barcelona and Bayern Munich were reportedly also pursuing Luiz, who has spent three-and-a-half seasons at Stamford Bridge.
The 27-year-old joined from Benfica in January 2011, signing a five-and-a-half-year contract in a deal reportedly worth £21m.
He has made 143 Blues appearances - 34 of them last season, including against PSG in the Champions League quarter-finals - scoring 12 goals.
Luiz was primarily used in defensive midfield by Jose Mourinho after being unable to break up the central defensive partnership of John Terry and Gary Cahill.
His departure means Tomas Kalas will be given further first-team opportunities next season while Kurt Zouma, signed from St Etienne in January and immediately loaned back to the French side, will also link up with the Blues.
Luiz's sale represents a healthy profit which Mourinho will hope to reinvest in the squad, with Atletico Madrid striker Diego Costa reportedly the number one target.
PSG have also been linked with Eden Hazard and Oscar in recent months, but Chelsea would not welcome an approach for the playmaking pair.
There was the prospect of further high-profile departures from Stamford Bridge when the Premier League announced its retained and released players' list.
Chelsea's record goalscorer Frank Lampard appeared on Chelsea's list as uncertainty continues over his future.
England midfielder Lampard, who is 36 in June, appeared on the list alongside striker Samuel Eto'o and left-back Ashley Cole as their contracts expire on 30 June.
Lampard's appearance does not mean his departure is inevitable, although Chelsea are still to clarify if the midfielder, who moved to Stamford Bridge in June 2001, will stay or move on.
Cole has suggested he is likely to leave Chelsea, while Eto'o is poised to move on at the end of his one-season deal.
Lampard has scored a club record 209 Chelsea goals in 646 appearances since his switch from West Ham, including the two goals at Bolton which secured the 2004/05 Premier League title.
That was Chelsea's first championship for 50 years and began the most successful period in the club's history.
Eto'o netted 12 times in 35 appearances last term following his move from Anzhi Makhachkala.
Cole has hinted his future lies away from Stamford Bridge after eight years having fallen down the pecking order last term.
The former Arsenal left-back, who retired from England duty after winning 107 caps but being overlooked for the World Cup squad, has been linked with moves abroad and to Manchester United and Liverpool.
Goalkeepers Mark Schwarzer and Henrique Hilario also appeared on the list - a Premier League requirement - alongside youngsters including Sam Hutchinson and Milan Lalkovic.
