Chelsea, Conte has two doubts ahead of Champions League game against Roma

Two doubts for Antonio Conte ahead of the game against Roma: it will be either Zappacosta or Rudiger in the 3-5-2 formation for Chelsea and then Kante or Drinkwater in midfield. If Conte chooses Rudiger, Azpilicueta will play on the wing. Azpilicueta will play at center back, if Zappacosta plays as right back.

Here is the probable formation: Courtois; Azpilicueta, David Luiz, Cahill; Zappacosta, Kante, Bakayoko, Fabregas, Alonso; Hazard, Morata.
