Both players starred in the 6-0 win at Stamford Bridge as Batshuayi scored a brace while the Danish defender was also impressive at the centre of the back-three.
Following the game, Conte said: “I wanted to give a good chance to Michy, and also to Christensen. To play in the Champions League means the coach trusts you. My message tonight was this. I trust all my players, not only with words but with facts.
“For the first game in the Champions League I decided to start with rotation. Also because we have to start the process to improve our players.
“If we think we can play with 13 players like last season, we are crazy. Instead, we have to improve our players and try to create a good competition between them. A positive competition is very important.”
