It was all going so well for Pep Guardiola at Manchester City after 10 games.
Ten consecutive wins had many already placing the Premier League crown on Guardiola's head, however, things have certainly derailed of late at the Etihad.
Four matches without a win meant Sunday's clash with Southampton had slightly greater importance than it might have done a few weeks ago.
And it didn't get off to the best of starts.
Guardiola changed to 3-5-2 formation and captain Vincent Kompany made his first Premier League start since April but it wasn't enough to turn the team's fortunes around.
With less than half an hour on the clock, the home side were behind after Nathan Redmond capitalised on a horrendous error from John Stones.
There was seemingly no danger when the English centre-back collected the ball deep in his own half.
But a misplaced pass aimed for Kompany proved to be the perfect through ball for Redmond, who then went round Claudio Bravo to calmly break the deadlock.

Just a few minutes later, Stones thought he had made up for his error when he headed past Fraser Forster.
And he wasn't the only one, Sky Sports started showing the replay of the finish and even credited City with the goal on the scoreboard.
However, after a few moments of confusion, it was revealed that referee Mark Clattenburg had ruled it out for Sergio Aguero being in an offside position.
