David Luiz is on the verge of a Chelsea return, two years after being sold to Paris St Germain for £50million.
The Blues and PSG announced terms had been agreed for the Brazil defender to return to Stamford Bridge from Parc des Princes.
"Chelsea Football Club and Paris St Germain have agreed terms for the transfer of David Luiz back to London," Chelsea said on their official website.
"The move is now subject to him agreeing personal terms and passing a medical."
Luiz won the 2012 Champions League and 2013 Europa League with Chelsea before moving to PSG prior to the 2014 World Cup.
His likely acquisition was part of a busy deadline day for the Blues, who signed Marcos Alonso from Fiorentina and loaned Juan Cuadrado back to Juventus for three years.
Luiz joined Chelsea from Benfica in January 2011 and made 143 appearances, scoring 12 goals, before his departure three-and-a-half-years later.
The 29-year-old has played against Chelsea four times in the two years since leaving the Blues, as PSG were opponents in the Champions League in each of the last two seasons.
He vowed not to celebrate if he scored against his former club, but did so as PSG advanced on away goals at the expense of Chelsea in March 2015.
He is the latest former player to return to Chelsea. The Blues bought back Nemanja Matic, who joined Benfica as part of the deal which saw Luiz signed, while Didier Drogba recently had a second spell at Stamford Bridge.
