Defeat of Manchester City and Brighton, fourth in a row.
Pep Guardiola has never lost four times in a row in his 16-year coaching career.
Although only two of the four defeats came in the Premier League (from Bournemouth, and now from Brighton, the others were from Tottenham in the League Cup and Sporting in the Champions League), City risks a significant gap in the standings before the break.
That will happen if Liverpool beat Aston Villa tonight - the difference will be five points.
Guardiola's team is paying for this season's frightening rhythm of winning, which they have imposed on themselves, but also through injuries. There is no Rodrigo Ballon d'Or, De Bruyne has just recovered (he came on tonight in the second half), so this crisis of results had to come.
He led City with a goal by Erling Haaland in the 23rd minute - the Norwegian opened up everything and put the ball into the net after a great pass from Kovacic, but Brighton were the better team in the rest.
Fabian Hirzeler's men besieged City's goal like wasps, and as a reward came goals from Brazilian Joao Pedro in the 78th minute and Dane Matt O'Reilly in the 83rd minute.
In the end, City made a real siege on the "seagulls" goal, but the score remained 1:2... Brighton is fourth in the table, level on points with third-placed Nottingham Forest.
