Why is Pierre-Emerick Aubameyang wearing a mask?

Given Pierre-Emerick Aubameyang made a name for himself as the striker who celebrates his goals wearing the masks of superheroes, Chelsea may see it as a good omen that his life at the west London club will begin in one.

Aubameyang emerged on Monday night at the Stadion Maksimir in Zagreb, where Chelsea’s Champions League campaign kicks off on Tuesday, wearing a protective face mask one week after his jaw was broken by intruders that had broken into his Barcelona home.

At Arsenal and Borussia Dortmund, characters such as Batman, Spiderman and Black Panther were all pulled out in celebration, so Chelsea now wait to learn whether Aubameyang can be their masked Marvel.
