Forward Alexis Sanchez will leave Arsenal in January if a suitable offer arrives and a replacement is secured.
It is understood the Gunners hierarchy have accepted that Sanchez is likely to depart after three and a half years.
However, Arsenal are reluctant to sell without replacing the Chilean and their first choice is Bordeaux’s 20-year-old Brazilian forward Malcom.
“Normally he would stay until the end of the season but we’ll see,” said manager Arsene Wenger.
Speaking at a news conference on Friday, the Frenchman added: “Nothing is really concrete at the moment and nothing is decided one way or another.”
