The Blues were the underdogs before the match started but they stunned the favorites by denying them the space to operate restricting Man City to just one short on target in the match.
Kai Havertz rounded Ederson to tap into an empty net following a through pass from Mason Mount to give Chelsea a deserved lead just before halftime.
Chelsea survived a late onslaught by Manchester City to win the trophy nine years after winning it for the first time in Munich.
Havertz revealed after the match that he worked 15 years for such a big moment.
“I don’t know what to say, I waited a long time. I’ve worked 15 years for this moment, I am overwhelmed,” 21-year-old Havertz said.
Ngolo Kante won the man of the match award following an impressive performance in the final.
