Chelsea are looking to extend our unbeaten run to seven games since we were eliminated on penalties to Tottenham in the Carabao Cup. Our only defeat in 90 minutes this season (11 games) was against Liverpool when we played the last 50 minutes with 10 men.
Wednesday will be our 99th game in the group stage of the Champions League and we need one point to reach 200 in the 17 seasons we have been in the competition (excluding the second group stage in 1999/2000).
Frank Lampard’s side are unbeaten in seven Champions League group matches since our home defeat to Valencia on matchday one last season (four wins, three defeats).
The Valencia defeat is the only one in our previous 15 home games in the competition, We have won nine and drawn five of those.
Chelsea are looking to keep a clean sheet in three consecutive Champions League matches for the first time since October/November 2013 against Steaua Bucharest and Schalke twice.
The last occasion we started a campaign with three consecutive clean sheets in the group stage was in 2009/10 when Carlo Ancelotti was in charge.
Edouard Mendy has kept five clean sheets in his six appearances for the Blues and has only conceded one goal which was on his debut against Tottenham.
Hakim Ziyech has been directly involved in 13 goals in his last 15 starts in the Champions League, scoring six goals and assisting a further seven.
Ziyech is the first player to score in his first two starts for Chelsea since Diego Costa in August 2014.
If selected, Olivier Giroud will make his 50th start for Chelsea in all competitions.
Against Burnley, Kurt Zouma made his 100th start for the club and Mason Mount started for the Blues for the 50th time.
