Frank Lampard’s Chelsea have now lost four of their last five Premier League games.
After the Blues’ bright start to the season, it is a poor run of form that has allowed other sides to fight back in the race to finish in the top four.
One of those sides is Jose Mourinho's Tottenham, who Chelsea face next weekend, and Lampard now faces a tough run of games as he looks to arrest the current slump.
As well as Spurs, the Blues travel to Arsenal before the year ends. These matches against Arsenal and Tottenham have raised in importance and Chelsea will not want to concede any more ground in the race for the top four.
Rare off-day for Chelsea attack
The likes of Mason Mount and Tammy Abraham have been shining lights for Chelsea season, but this Saturday was a different story.
Usually so crisp and sharp with their link-up play, the pair - and wingers Christian Pulisic and Willian - were kept at bay by Bournemouth.
Credit must go to Eddie Howe’s team for how they toiled away to keep the Blues’ attack out, but it was, without doubt, a rare off-day for the hosts.
Chelsea may have had problems at times in defence this season, but going forward they have been one of the most entertaining sides in the Premier League.
Saturday, however, was one of those matches were nothing would click and the Blues now need to quickly dust themselves down ahead of their trip to Tottenham next weekend.
Search for a clean sheet goes on
You have to go all the way back to November 9 to find the last time Chelsea kept a clean sheet.
Since then the Blues have conceded 11 goals in seven games in all competitions and they must tighten up at the back. Antonio Rudiger has returned from injury, but Chelsea still seem shaky when defending.
Bournemouth’s winner here may have been scrappy and hardly a contender for goal of the season, but they created other chances in the second half.
Rudiger and Kurt Zouma were both forced to make last-ditch challenges and it highlights how Chelsea are still a work in progress at the back.
Bournemouth love playing at the Bridge
Since gaining promotion to the Premier League in 2015, Bournemouth have played 27 away matches against the established top six. They have won - including today - just three of those games and all of those victories have come at Stamford Bridge.
It is a bizarre statistic, but one which underlines how much of a happy-hunting ground Stamford Bridge is for the Cherries. They have shocked Chelsea teams in the past and on Saturday they were once again worthy winners of the three points.
The Blues were lacking in sharpness and Bournemouth capitalised to end a run of five defeats thanks to Dan Gosling’s second-half goal.
