Arsenal manager Mikel Arteta has admitted he is unsure why Pierre-Emerick Aubameyang has returned to the club earlier than expected from the Africa Cup of Nations.
The 32-year-old striker was away on international duty with Gabon at the tournament but did not get to kick a ball in competitive action for his country due to contracting Covid-19 on the eve of the competition.
Ahead of Gabon's second group stage fixture against Ghana, Aubameyang was not selected due to fears over his health after tests determined he had suffered cardiac lesions during his time with Covid.
