Arsenal forward Pierre-Emerick Aubameyang has been treated in hospital after he contracted malaria while on international duty with Gabon.
He played in Arsenal's Europa League quarter-final first leg against Slavia Prague on 8 April but missed Sunday's win over Sheffield United.
"I've spent a few days in hospital this week," he said on Instagram.
"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 weeks but will be back stronger than ever soon!"
Malaria is a tropical disease spread by mosquitoes.
