Chelsea will be seeking a fourth win from four Europa League Group L games in Thursday’s contest.
They will be confirmed in first place with two rounds of matches to go if they win and the other game, between Vidi and PAOK in Budapest, is drawn.
Chelsea have now won six consecutive Europa League games, since a 2-3 defeat at Rubin Kazan in April 2013.
Chelsea have had the most shots in the competition so far (73), while also facing fewer than any other team (15).
Eden Hazard has travelled for Chelsea’s clash at BATE, but Marcos Alonso, David Luiz, Antonio Rudiger and Alvaro Morata have been left at home.
Sarri wants Hazard to get some additional match action, after his return last Sunday, and insisted the flight was not a problem for the Belgian.
