Conte, who joined Chelsea in 2016, led them to the league title in his first season but they have failed to challenge this term and sit fifth in the standings, 22 points behind City.
"If I remember well, two days ago, Arsenal played twice against them and then you criticise a lot Wenger because they concede three goals in only 30 minutes".
"But for sure when we chose to play with Pedro, Hazard and Willian there is a difficulty to have the players to change the game". We had to try and nullify them.
"It was hard. It felt like we were doing a lot of running and they had all the time in the world".
"We have had opportunities against Barcelona, but nothing at all today", he said.
Chelsea played winger Eden Hazard as a lone striker and operated a deep midfield in front of their backline, showing little ambition or attempt to press or counter-attack in numbers. We were sloppy on the ball sometimes. "It's frustrating because we could have drawn 0-0 and that wouldn't have been a bad result".
Chelsea are battling for Champions League football next season but defeat at City would leave Conte's side five points adrift of the last qualifying spot if their fourth-placed London rivals Tottenham Hotspur beat Huddersfield Town on Saturday.
"We need the balance".
"We are going to work hard to perform better next week".
