For a period in the second half at Wembley, Chelsea were unsettling City as their fans were sensed a repeat of the old habit of rescuing a season of turmoil with a trophy.
It was not to be as Chelsea were unable to find the finished product, leaving them vulnerable to the sort of game-changing moment Semenyo produced.
Chelsea must now try to ensure they will be playing football next season via the Premier League, starting against Tottenham Hotspur at Stamford Bridge on Tuesday.
And, following the sacking of Liam Rosenior, Chelsea must also now embark on another fresh start as they accelerate moves to appoint Xabi Alonso at their new head coach.
If the deal goes through, the arrival of one of Europe's most sought-after young coaches, who won the Bundesliga at Bayer Leverkusen before a short spell amid the dysfunction of Real Madrid, will bring renewed optimism.
And how Chelsea need that after this FA Cup final defeat and such a disappointing season.
