No, it is not an admin error.
Chelsea shocked the footballing community after revealing that technical advisor Petr Cech has been included in the club’s 25-man squad for the 2020-21 Premier League season.
The 38-year-old veteran was seen training with the squad few days ago and it has now been confirmed that he is coming out of retirement.

Chelsea’s goalkeeping troubles are no secret with mega-money signing Kepa having a torrid time in the post since his arrival.
But nobody could have predicted that the Spaniard will actually force Cech out of retirement.
Seriously though, it would be mental if Petr Cech ends up on the field at some point this season for the Blues.
Here’s the full 25-man squad –
Abraham, Tammy
Alonso Mendoza, Marcos
Arrizabalaga Revuelta, Kepa
Azpilicueta Tanco, Cesar
Caballero Lazcano, Wilfredo Daniel
Cech, Petr
Chilwell, Benjamin James

Kovacic, Mateo
Mendy, Edouard Osoque
