Chelsea have already qualified from their group, but have to win against their Romanian opponents to guarantee the crucial top spot.
Steaua Bucharest have nothing to play for though, and Jose Mourinho will be confident of picking up the three points that will ensure his side avoid the likes of Real Madrid, Bayern Munich or Barcelona in the last 16.
The Blues are without Andre Schurrle, and Oscar and David Luiz are unlikely to feature. Instead, Willian could play in attacking midfield, with Gary Cahill and John Terry should partner each other in the centre of the park.
