That's all from this week's Champions League coverage.
A day on from Erling Braut Haaland's stunning individual performance to down PSG, it was Atalanta's stunning team performance that stole the show against Valencia.
We'll be back next week for what should be four more thrilling matches.
On Tuesday, it's Chelsea vs. Bayern Munich and Napoli vs. Barcelona; on Wednesday, it's Lyon vs. Juventus and Real Madrid vs. Man City.
See you then!

I think it's fair to say Atalanta are happy with how their debut season in the Champions League is going.

That will be a night Jose Mourinho and Tottenham will want to forget.
Julian Nagelsmann got his game plan absolutely spot on and will be disappointed his RB Leipzig side didn't come away with a bigger margin of victory.
Nagelsmann has been dubbed 'Mini Mourinho' -- though admittedly it's not a nickname he's particularly fond of -- and is 25 years Mourinho's junior, but that is a performance even 'The Special One' would have been proud of in his managerial prime.
You can read all about a chastening night for Tottenham in our match report here.
Tottenham fans will be bitterly disappointed with that performance.
Aside from a late flourish, RB Leipzig dominated all match and it will take an almighty effort for Spurs to turn things around in Germany.
Timo Werner's penalty was the difference between the sides but, in truth, it could -- and should -- have been a lot worse for Tottenham.

You never would have guessed this was Atalanta's first ever appearance in the Champions League.
That was a stunning performance and Valencia was well and truly second best all night.
The only blemish on an otherwise perfect night was that mistake from Jose Luis Palomino that gifted Valencia a consolation goal.
However, as impressive as Valencia can be at its famed Mestalla stadium, you can't see this side turning things around in the second leg.

It's pretty unusual to see so many goals shared around the team like this, but it's certainly reflective of the expansive team game Atalanta plays.

RB Leipzig forward Timo Werner is making a habit of ruffling feathers in enemy territory.
The German has scored every one of his seven Champions League goals away from Leipzig's Red Bull Arena.
In fairness, Leipzig have very much made themselves at home tonight and played like the home side at the Tottenham Hotspur Stadium.

It's an awful error from Atalanta defender Jose Luis Palomino, whose sloppy pass across his defense gifts Denis Cheryshev possession.
The Russian has been on the field a matter of seconds -- in fact, that may have his been his first touch -- and he fires a low strike into the far corner.
A glimmer of hope for Valencia with an away goal.
Matias Grez
Just 62 minutes into this first leg, SURELY Atalanta has secured passage through to the quarterfinals.
Hans Hateboer runs onto the ball behind Valencia's ailing defense and hammers the ball into the back of the net for his second of the game.
In truth, that is awful goalkeeping from Jaume, the ball is straight at him but he moves out of the way.
There is a brief VAR check for offside but the goal stands.
Wow!
