Goalkeeper Petr Cech has been named in Chelsea's Premier League squad - despite having retired from playing at the end of the 2018-19 season.
The 38-year-old, who is the club's technical and performance adviser, was added as "emergency cover".
Elsewhere, midfielder Mesut Ozil has been left out of Arsenal's 25-man squad.
Manchester United have not included defender Phil Jones and goalkeeper Sergio Romero in their list.
Clubs had to name a 25-man squad after the closure of both the international and domestic transfer windows.
Cech spent 11 years as a player at Stamford Bridge, winning 13 trophies, including four Premier League titles and the Champions League.
