Arsenal captain Pierre-Emerick Aubameyang revealed he has been hospitalised after contracting malaria while on international duty with Gabon last month.

The forward missed Sunday’s 3-0 Premier League win at Sheffield United and was also absent for the Gunners’ Europa League quarter-final second-leg clash with Slavia Prague on Thursday. Arsenal had said Aubameyang was missing due to “illness” without going into detail but, just moments before his teammates kicked off in the Czech capital, the Gabon international posted the news of his illness on Instagram.

The 31 year old recently signed a lucrative three-year contract last year but has struggled for form this season and was dropped for last month’s north London derby after arriving late.

He has managed just nine goals in 25 Premier League appearances this season compared with 22 goals last term.
