Pierre-Emerick Aubameyang has returned to the Premier League after leaving Barcelona.

The forward was announced as a Blues player after the transfer window closed after a deal with Barcelona was agreed earlier in the day, with Marcos Alonso believed to be moving in the opposite direction.

Aubameyang’s shirt number, however, is a contentious one, as it replaces one that has a troubled history at Stamford Bridge. The 33-year-old will be the club’s new No.9, replacing Romelu Lukaku, who left on a season-long loan earlier this summer.

Tammy Abraham was the next most successful player to wear the shirt in recent memory, despite a track record of failure for those who have worn the iconic top. Steve Sidwell, Franco Di Santo, Fernando Torres, Radamel Falcao, Alvaro Morata, and Khalid Boulahrouz are also wearing the shirt.
