Chelsea fans will have to wait until Monday afternoon to see their players kick off in Qatar, firstly with Mason Mount, Conor Gallagher and Raheem Sterling with England against Iran. Later that day, Edouard Mendy, Christian Pulisic and Ethan Ampadu will begin their campaigns for Senegal, USA and Wales, respectively.
Given the Blues' disappointing start to the season, a fresh change of environment can hopefully give several underperforming players the chance to regain some confidence and form ahead of the return to west London after Christmas.
With 15 players either currently in the squad or on loan at other clubs in Qatar, football.london takes a look at the Chelsea names who need a big tournament.
