Chelsea have confirmed they have agreed a deal to re-sign David Luiz from Paris Saint-Germain.
Sources told ESPN FC earlier on Wednesday that Chelsea were confident of signing Luiz, 29, even though PSG were holding out for an offer of between £40 million and £45m for the defender.
The Brazil international arrived in London later in the day and Chelsea -- who have already sealed the signing of Marcos Alonso from Fiorentina -- have confirmed that a fee has been agreed with the Ligue 1 champions.
A statement on Chelsea's official website read: "Chelsea Football Club and Paris Saint-Germain have agreed terms for the transfer of David Luiz back to London.
"The move is now subject to him agreeing personal terms and passing a medical."

PSG posted the same message on their official site.
A source said that Chelsea had considered Aymen Abdennour on loan from Valencia as a backup option after PSG initially said Luiz was not for sale on Tuesday evening, but the Ligue 1 club's stance then softened.
Luiz moved to Parc des Princes from Stamford Bridge in 2014 in a £50m deal and won nine trophies as part of a team that completed two consecutive domestic clean sweeps under former boss Laurent Blanc.
He has started all four of PSG's competitive fixtures so far this season. However, Le Parisien reported earlier this month that new coach Unai Emery has told the 29-year-old that he is no longer guaranteed a starting role.
Captain Thiago Silva is back in training after a hip injury and expected to be available after the international break, while his Brazilian compatriot Marquinhos has returned from Olympic duty in Rio de Janeiro triumphant and is available once again. Both figure ahead of Luiz in Emery's reported pecking order.
