Chelsea face Arsenal on Saturday in what will be Maurizio Sarri's first competitive home game in charge of the Blues.
The club's new manager will be hoping to follow up his side's 3-0 win over Huddersfield by beating the Gunners, who suffered a defeat to Manchester City in their Premier League opener.
Unai Emery is also new to English football but he has already faced Sarri in a pre-season match in Dublin, with north Londoners eventually winning on penalties after a 1-1 draw.
Chelsea Injuries
Chelsea have only one injury concern and that is Cesc Fabregas, who is a major doubt after suffering a knee injury against Arsenal in pre-season.
