Arsenal have revealed that Pierre-Emerick Aubameyang and Alexandre Lacazette missed Arsenal's season opener - which ended in defeat to Brentford - after testing positive for coronavirus.
Brentford enjoyed an incredible introduction to the Premier League after the newly promoted team shocked the Gunners in the season's opener. The Bees announced their arrival in the top flight in style as goals from Sergi Canos and Christian Norgaard secured a memorable 2-0 win.
The club said Aubameyang could make a return to action in Sunday's clash against Chelsea, but forward Lacazette is likely to sit out again.
"Auba is now negative on Covid-19 testing, is well and following all protocols for return to play," Arsenal said in a statement.
"He will return to training and be assessed prior to Sunday's match. Alex is still recovering and will not be available."
Winger Willian and goalkeeper Alex Runarsson also tested positive.
The club said Willian was adhering to protocols and that his health will be assessed ahead of the Chelsea game, while Runarsson is still in the recovery process.
Arsenal are already without Thomas Partey (ankle), Gabriel Magalhaes (knee) and Eddie Nketiah (ankle).
