However, Conte refused to put the blame on the Denmark international who made his 14th appearance in the competition since his debut with Borussia Mönchengladbach in 2015 during a loan spell from the Premier League champions.
"I think Christensen's performance was a very good performance, an incredible performance. We are talking about a player who is only 21 years old here," Conte said after the game, as quoted via Sky Sports.
"It's great that he is able to play this game with maturity and personality. I am very happy. He was one of the best players tonight."
