Arsenal has agreed on an £8m deal with Chelsea to sign defender David Luiz on a two-year contract.
The 32-year-old Brazil international, signed a new two-year Chelsea deal in May, will have a medical at Arsenal on Thursday.
The centre-back first joined Chelsea in 2011 from Benfica where he stayed for three years.
He then moved to Paris Saint-Germain in 2014 and then returned to the Blues in 2016.
The Brazilian has won the UEFA Champions League, UEFA Europa League (twice), English Premier League, FA Cup (twice) with Arsenal’s London rivals, Chelsea.
He also has won the Ligue Un, Coupe de France, and many other domestic trophies with the French giants, PSG.
However, 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.
The Gunners conceded 51 goals in the league last season.
They also lost the Europa League finals to London rivals, Chelsea, the club the Luiz joins Arsenal from.
Unai Emery has been keen on improving the squad and the addition of the Brazilian could prove to be the turning point.
