- Joao Pedro hands Chelsea the advantage in the first half.
- Atalanta the better side after the break and equalise through Gianluca Scamacca.
- The Belgian attacker scores a late decisive goal for the home side.
- The defeat means Chelsea slide to 11th in the group stage of the Champions League.
- The leading eight teams progress automatically for the last 16.
Chelsea's hopes of securing a place automatically for the Champions League knockout stages were dealt a blow as their Italian opponents came from behind to triumph in their home stadium.
The two teams went into this game with matching records in the initial stage of this season's competition, having secured three victories, drawn, and lost to have accrued 10 points.
For much of the game there was not much to separate them in this contest too, even though Chelsea went ahead in the first half when the Brazilian finished the captain's cross.
But Atalanta consistently appeared a danger going forwards, with ex- Premier League attacker creating issues for the defence.
Reece James fired wide in the after the break but Atalanta increased the intensity and justly levelled when ex-West Ham striker Gianluca Scamacca a centering pass.
The winger drove a powerful shot straight at the goalkeeper but Atalanta got the winner in the closing stages when the Blues defence retreated from the midfielder, who seized the opportunity with a low shot.
Chelsea tried to rescue a point in stoppage time but a excellent save by Marco Carnesecchi kept out Pedro.
The outcome means Chelsea drop out of the top eight—the positions that qualify automatically for the knockouts—to eleventh with two group stage fixtures left to play.
The Bergamo club, in contrast, climb up to third place, three points ahead of the Blues.
Chelsea Analysis - Concerning Sequence Continues
This was a hugely disappointing result for Chelsea as even a draw was leaving them in a strong position to achieve the top-eight position they need to bypass the uncertainty of the play-offs.
But they lacked concentration in their defensive duties with seven minutes remaining and their opponents capitalised completely.
The Italians are in rich vein of form at the moment so this was always going to be a challenging examination for the visitors, but they will be annoyed to be departing with nothing after taking the lead.
But the wider issue is that this perpetuates Chelsea's troubling streak of results in all tournaments.
Since defeating Barcelona 3-0 at the end of November they are now winless in their last four outings.
Excessive Rotations Turning Out to Be Expensive?
Chelsea boss Enzo Maresca made five changes for this game as he persisted with his policy of moving players in and out of the first team.
The rotations here came after he made the same number for the loss to Leeds United and six for the tie with Bournemouth prior to the trip to Bergamo.
Maresca will view squad rotation as essential as he attempts to manage players' minutes and compete both at home and in Europe, but he maintained the central contingent of players stays the same for important fixtures.
"I think in this match [in] the starting lineup we had eight or nine players who played against Tottenham, FC Barcelona, and Arsenal," he said.
"If you look at the five changes that we made compared to the previous game it is different but it is the eight or nine players who played in that match.
"The players who played tonight are the individuals who feature in almost all the games."
What Next for These Sides?
Chelsea's next Champions League fixture sees them host Pafos on the coming Wednesday (8pm GMT).
The Italian team, on the other hand, host Athletic Bilbao at the identical kick-off time.
