Chelsea defeated English rival Manchester City, 1-0, in Porto, Portugal, to triumph in the Champions League final Saturday, winning the European competition for the first time since 2012.

The underdog went ahead shortly before the break on a brilliant pass from Mason Mount to Kai Havertz, who got behind the City defense and beat goalkeeper Ederson to score his first Champions League goal.

Manchester City, which secured the Premier League crown two weeks ago, was favored to win the competition for the first time in club history, despite losing to Chelsea twice in the past two months. Coach Thomas Tuchel had revitalized Chelsea since he joined the club in January, leading it to a top-four Premier League finish.

Christian Pulisic replaced Timo Werner in the 66th minute, becoming the first U.S. men’s national team player to see the field in a Champions League final

His substitution came as each team continued to freshen their sides. City’s Fernandinho replaced Bernardo Silva in the 64th minute.

Shortly after entering, Pulisic came close to doubling Chelsea’s lead but pushed his 72nd-minute shot just wide.

Manchester City star Kevin De Bruyne was treated for several minutes following a 56th-minute collision with Chelsea defender Antonio Rüdiger that led both to require medical attention. De Bruyne was replaced by Gabriel Jesus when he returned to his feet and Rüdiger was shown a yellow card.
