Premier League duo Arsenal and Chelsea have agreed £8m deal over the transfer of defender, David Luiz on a two-year contract from Stamford bridge to Emirate Stadium.
David Luiz, 32 who just signed a new two-year Chelsea deal in May, will have a medical at Arsenal on Thursday.
On Tuesday, Arsenal sold defender Laurent Koscielny to French side Bordeaux for a fee of up to 5m euros (£4.6m).
They are also set to sign Celtic left-back Kieran Tierney for £25m.
Luiz has spent six and a half years at Chelsea during two spells and has made 160 Premier League appearances, scoring 11 goals.
His departure, if confirmed, comes five weeks after Frank Lampard returned to Stamford Bridge to manage his former club.
The Blues are currently serving a transfer band until the end of January 2020 following an investigation into their signing of foreign under-18 players.
With Gary Cahill, who has since joined Crystal Palace, released at the end of last season, Chelsea’s options at centre-back include Germany’s Antonio Rudiger, Kurt Zouma, who was on loan at Everton last season, and Denmark’s Andreas Christensen.
Having signed a £21m deal in January 2011 for Chelsea from Benfica, Luiz joined Paris St-Germain for £40m in June 2014 before returning to Stamford Bridge for £34m in August 2016.
Luiz was present at Chelsea’s Cobham training ground on Wednesday, although he did not take part in first-team training.
