Chelsea have qualified for the FA Cup final after Hakim Ziyech's second-half goal at Wembley ended Manchester City's wait for a quadruple.
The Moroccan's goal in the 55th minute was the game's only goal, ensuring the Blues a place in their fourth final in five seasons, where they will face either Leicester or Southampton.
The left-footed winger had earlier had a goal disallowed for offside, while Ben Chilwell also wasted an excellent chance to open the scoring for Chelsea.
WATCH THE GOAL HERE:
City went into Saturday's semi-final with hopes of becoming the first English club to win the Premier League, Champions League, FA Cup, and League Cup in the same season.
Indeed, this cup exit means Guardiola’s men can no longer do the Double or Treble either.
However, though Chelsea manager Tuchel was celebrating his first win over Guardiola in six tries, the Spaniard had only himself to blame for the surprising loss.
The Etihad boss had disrespected the rivalry once again by fully shuffling his pack with EIGHT changes.
