Facing Atletico Madrid at the Vicente Calderon in Europe was always a tough task.
The home fans created an incredible atmosphere and their home record helped them reach two Champions League finals in the previous four seasons.
But will Atleti's new Wanda Metropolitano Stadium be equally difficult to get a result from?
Well, it was Chelsea who had the privilege of becoming the first team to play there in a European competition - and they came away with all three points.
Atleti may have taken a first-half lead through Antoine Griezmann’s penalty but Chelsea fought back and equalised with Alvaro Morata.
And just when it looked as though both sides were going to settle for a point, Michy Batshuayi popped up with a goal with the last kick of the game. Literally.
The Chelsea players, fans and Antonio Conte went crazy, while the Wanda Metropolitano was stunned as Diego Costa hung his head in despair.
There wasn’t even enough time to Atletico to restart the match with the referee blowing for full-time.
After finishing their jubilant celebrations, the Chelsea players went down the tunnel into the dressing room to take numerous celebratory selfies.
But before he could pose for any photos, Batshuayi had something to do.
Batshuayi's post-match tweets
He immediately went to Twitter to upload an image he’s clearly been saving for a special occasion. It’s an image of his face photoshopped on Batman - his nickname - with the Chelsea badge in the background.
And Batshuayi wrote: “When the game needs a 94th minute winner call me #Batsman.”
The tweet was posted at 9:58pm, which is just minutes after the full-time whistle.
Well played, Michy.
That wasn’t the striker’s only tweet of the night, though.
He did then upload their customary celebratory selfie in the dressing room, writing: “More seriously, I'm happy to score the winning goal but what a great game we had !!! Terrific team performance enjoyed it all.”
He then went back to the Michy we know and love by tweeting about EA Sports and his poor FIFA rating.
He then posted an image alongside Costa and Fernando Torres with the caption: “Great honour to meet one of the great strikers I used to watch when I was younger ... and no Im not talking about Diego.”
