Arsenal forward Pierre-Emerick Aubameyang has been treated in hospital after contracting malaria while on international duty with Gabon.
The 31-year-old scored in Gabon's 3-0 win over DR Congo in Africa Cup of Nations qualification on 25 March.
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 [illness] 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. Symptoms usually appear seven to 18 days after infection, but it is not contagious.
