Aubameyang took to social media to explain why he was not involved against Slavia Prague in the crunch quarter-final tie on Thursday night, posting a picture of him in hospital.
He admitted that he had not been feeling himself for the past couple of weeks but vowed to be back ‘stronger than ever’ once he has fully recovered.
‘Hey guys, thanks for all the messages and calls,’ posted Aubameyang on Instagram.
‘Unfortunately I contracted Malaria whilst being on national team duty in Gabon a few weeks ago.
‘I’ve spent a few days in hospital this week but I’m already feeling much better every day, thanks to the great doctors that detected and treated the virus so quickly.
‘I wasn’t really feeling myself the last couple [of] weeks but will be back stronger than ever soon! 🙏🏾
‘Will be watching my boys now, huge game for us! Let‘s go and get it.’
In Aubameyang’s absence, Alexandre Lacazette leads the line for the Gunners.
Bukayo Saka, Emile Smith Rowe and Nicolas Pepe will provide support in attack.
