Brazilian centre-back David Luiz will leave Arsenal this summer.
Luiz has made 30 appearances in all competitions this season but the Gunners feel they need to look towards the future after a torrid campaign.
It is not known whether the former Paris St Germain and Chelsea defender intends to remain in England.
Luiz, who joined from London rivals Chelsea for £8m in August 2019, has missed Arsenal's last three games with a hamstring injury.
Mikel Arteta's side are ninth in the Premier League.
