New signing Hakim Ziyech will wear 22, vacated by Christian Pulisic who has been given 10 following the departure of Willian.

The 11 most recently worn by Pedro has been handed to Timo Werner, while another summer acquisition, Kai Havertz, will take the 29 shirt. Fikayo Tomori switches to 14.

Our two new defenders, Ben Chilwell and Thiago Silva, will wear 21 and 6 respectively.

With Michy Batshuayi moving out on loan, Billy Gilmour becomes 23.

Replica shirt exchanges

We are aware that some supporters may have already purchased the new 2020/21 home shirt (launched 9 July 2020) and/or the new 2020/21 away shirt (launched 30 July 2020) with previous squad numbers on the back.

We will be offering anybody who has proof of purchase from an official club store a free exchange, subject to availability, from today until 9 October 2020. All returned shirts will be donated to the Chelsea Foundation.

• For those who purchased from the Stadium Megastore at Stamford Bridge, simply return the 2020/21 home or away shirt with proof of purchase in person for a replacement.

• For those who purchased from the club's official online store (ChelseaMegastore.com) return the 2020/21 home and/or away shirt by post with a copy of the order confirmation email(s) to the store you made the original purchase from. A replacement like-for-like shirt will then be sent to you by post free of charge.

• For those purchases from non-Chelsea Football Club outlets, the club will offer a 50 percent discount on a purchase of a new 2020/21 home and/or away shirt, upon return of the existing 2020/21 shirt(s) with proof of purchase. This offer is only eligible to those who can visit the Stadium Megastore at Stamford Bridge in person.
