Extremely crappy start for Real Madrid (especially Courtois's mistake), I hope that at least at the end of the game the return game will still make sense. Real Madrid knows how to do miracles but no one can do them endlessly.
WTF, what a first half. Who would have expected Real Madrid to come back like that after being down 2-0, crazy.
If the teams continue to score goals at this pace, what will be the final score? 
Haha, if they continue like this Vinícius Júnior will surely strike a hat trick. Pretty interesting to see how LFC comes out of the halftime and if they can recover from this two maor setbacks.
And the Napoli Frankfurt game goes as expected tbh. Napoli is the stronger team (by far) and a lot closer to a 2:0 score than Frankfurt scoring a lucky 1:1.
/edit: 4:2 Real Madrid, WTF.
/edit: And Napoli 2:0. As expected.
Napoli with nice lead but that red card for Eintracht player seemed way to harsh to me. Again I have just seen one replay of situation and while it is a dangerous challenge there was no intention to harm the player, feels like yellow would be more appropriate but maybe it looks different from some other angle.
