Havertz’s first-half goal determined Porto’s final, which helped Chelsea complete the second Champions League victory.

Chelsea’s Kai Havertz repaid part of the huge transfer fee as his first-half goal defeated Manchester City 1-0 in Saturday’s Champions League final.

Chelsea’s signing of the German youngster stopped the ball on a pass from Moson Mount, evaded city goalkeeper Ederson, and then pushed the ball into the empty net in the 42nd minute.

The Premier League champion city was the most popular before the final, but after a disappointing night in Porto, it was their first time participating in the Champions League final.

Pep Guardiola’s team was never allowed to play normal fluent games and was unable to respond due to the disciplined Chelsea winning the Champions League again.

Chelsea boss Thomas Tuchel won the tactical battle with Manchester City’s Guardiola. If Timo Werner converted two gold-plated opportunities, his team could have won more. Big victory.

After a vacation, Manchester City struggled to find vacancies. When organizer Kevin de Bruyne was injured in a head clash, their career was not helped.

Chelsea spent a seven-minute pause, and Riyad Mahrez approached Manchester City painfully before starting the celebration of Chelsea fans.

The London club may have finished fourth in the Premier League, 19 points behind the Champion City, but this is the third time they have beaten Guardiola in six weeks.

When they won the FA Cup semi-final in April, they shattered Manchester City’s hopes of becoming the domestic triple crown, and then won in Manchester and postponed the championship celebration.

Now, with only more than 14,000 fans watching for the last time, they have created a boisterous atmosphere. They deny that Manchester City and Guardiola are so eager to win the Champions League.
