The two summer additions scored their first goals for the club in the 6-0 Champions League rout.
On Zappacosta, Conte remarked: “He played a really good game but now he has to continue to work to improve. For sure he knew very well my style of football and my idea of football. For this reason, I decided to start with him. He was prepared to play. He played very well.
“For him it was his first appearance at Stamford Bridge. It’s not easy to totally change your sporting life in one week, but the answer was very good. He has said he wanted to cross, but he scored and it’s important for us.
“I am very pleased with the performance. Now we have to continue in this way with him and the other players. I had a positive answer from my players tonight.”
Bakayoko, another summer signing, also netted his maiden goal for the Blues.
“To score is always important, above all when you play at home in front of your supporters in the first Champions League game. For a young player like him it was very important.
“Baka is improving his physical condition a lot. He is a strong player, a physical player, and he has to continue to improve and go better in our idea of football. He needs more time than Zappacosta.”
