A first-half goal from the summer signing of Kai Havertz, the most expensive player in Chelsea history, was enough to secure Thomas Tuchel’s victory in front of thousands of fans at Estadio Dragao in Porto, Portugal .
Meanwhile, Manchester City’s wait for European glory continues after making their first final in this season’s competition.
Chelsea, who last won the Champions League in 2012, were worthy of victory after executing a perfect game plan devised by Tuchel, who succeeded club legend Frank Lampard in January.
The former Paris Saint-Germain boss, who lost to Bayern Munich in the final last season, was a lively figure throughout, leading the 16,500 fans in attendance and urging his team to a famous victory.
“They (the players) were determined to win this. We wanted to be a stone in their (Manchester City) shoe,” an emotional Tuchel told BT Sport after the game.
“We encouraged everyone to get up and go out, to be more courageous and to create dangerous counterattacks.”
Both teams had chances throughout, but it was Havertz who kept his cool, latching on to a magnificent deep ball from Mason Mount to get around the goalkeeper and pass into an open net moments before the half time.
The wait for the city continues
Both teams lost key players in the final. Veteran Chelsea defender Thiago Silva was injured in the first half and City captain Kevin De Bruyne had to be replaced in the second half after colliding with Antonio Rüdiger.
But even before losing their talisman, City lacked quality and couldn’t cope with the constant pressure from Chelsea, led by man of the match N’Golo Kante.
Despite its domestic dominance, the Champions League has been the thorn in Manchester City’s side in recent years.
Manager Pep Guardiola, widely regarded as one of the greatest managers of all time, has not won the title since leaving Barcelona in 2012.
Three seasons have come and gone at ineffective Bayern Munich in Europe and they had failed to make it through the quarter-finals in their first four years at City.
He has at times been accused of overthinking his tactics when it comes to timing the Champions League, often to the detriment of his own side, and it appears he suffered a similar fate on Saturday.
Guardiola opted for an attacking formation without a single midfielder and his side failed to dominate the proceedings as usual.
Despite the disappointment, City still end the season as Premier League and League Cup champions.
“It was an exceptional season for us. It was a close game. We had chances,” Guardiola told BT Sport after the game.
“We were brilliant in the second half, we were brave and we couldn’t convert the chances because they were so strong. The players were exceptional. We may come back one day!”
In truth, Chelsea could have scored more. Forward Timo Werner missed two glorious chances in the opening stages and Christian Pulisic shot wide in the second half.
Although he missed his chance, Pulisic made history. When replaced by Werner in the second half, he became the first American to make a Champions League final and also became the first American to win the Champions League.
Chelsea’s Edouard Mendy has also made history, becoming the first African goalkeeper to make a Champions League final.
Mendy’s clean sheet is his ninth in 12 Champions League appearances this season, the most in a single campaign.
Mount, 22, who went through the club’s academy, struggled to contain his emotions after the final whistle.
“To go to the end of the Champions League. We have faced difficult teams. We are in the final and we have won it,” he told BT Sport. “It’s such a special occasion. Right now we’re the best team in the world. You can’t take that away from us.”
As Chelsea celebrated with fans inside the stadium, groups of supporters gathered in London to watch their team win Europe’s biggest football competition for the second time.
