Chelsea are champions of Europe, as they beat Manchester City 1-0 to lift the UEFA Champions League for the second time in their club history.
Chelsea are champions of Europe, after they got the better of Manchester City for the third time this season.
Kai Havertz, blossoming after a slow start to his Chelsea career, got the winner three minutes before half-time when he collected a defence-splitting pass from Mason Mount to round City goalkeeper Ederson and score.
It leaves City still searching for the Champions League, the trophy that has always eluded them, and Guardiola cannot escape scrutiny for his part in this defeat after taking a tactical gamble which backfired.
Guardiola surprisingly decided against utilising either Rodri or Fernandinho as a defensive midfielder, leaving City with a muddled game plan that reduced their effectiveness and rarely presented Chelsea with any problems.
Chelsea had the better opportunities throughout, Timo Werner wasting two good chances before Havertz struck and substitute Christian Pulisic squandering another in the second half.
City, who lost Kevin De Bruyne to injury midway through the second half, threw on Sergio Aguero for his final appearance but there was no fairytale ending for the club’s greatest goalscorer as Chelsea closed out the win.
And for Tuchel it was elation after the disappointment of losing last year’s final as manager of Paris St-Germain.
Tuchel made it three out of three against Guardiola by producing a fiercely disciplined, positive Chelsea performance that has brought a season that was shrouded in uncertainty to the most glorious conclusion.
The German has transformed Chelsea since his arrival in January, making significant changes by restoring the towering Antonio Rudiger in central defence and playing the magnificent man-of-the-match N’golo Kante in the position in which he is quite simply a world-class operator.
Kante controlled everything from his position in midfield, the complete player giving a breathtaking performance.
Chelsea needed to be defensively perfect but this was no smash-and-grab result. It was a front-foot display to take the initiative away from City in the first half.
They even survived the first-half loss of the experienced Thiago Silva to injury and carried on in the same measured, committed fashion.
It is a huge personal triumph for Tuchel, who already had victories against Guardiola in the FA Cup semi-final and in the Premier League at Etihad Stadium going in to this game.
And the confidence and self-belief those victories brought was in evidence as Chelsea played with a fearless attitude that never allowed City to settle and sparked wild scenes of celebration among players, staff and the fans inside Porto’s Estadio do Dragao.
The scale of Tuchel’s achievement is that this night was barely imaginable when he arrived in January but now Chelsea are champions of Europe for a second time.
