So why didn't it go to penalties? 

What a match.. Devoured a bag of chips in extra time... That frustration from Diego Costa is scary

Zalatan is forgiven after all. CRAZY!

if you can't win against 10 men (for the majority of the game) you clearly didn't deserve to go through.

idk something soft and calming. Kinda like elevator music.

Chelsea drew at home with a higher number of goals. That's the explanation, no logic behind it.

It's unfair that one team gets an extra 30 mins to get an away goal. 

oh dear, expected more from Chelsea but alas, I expect no England teams to be in it after this round. A few years ago it was 3 in the semis, now this. I blame Liverpool for taking Man Us spot. :P

It's not a comparison at all.  I'm shocked UEFA have its like that.  When it goes to extra time after 2 legs away goals should no longer count.  That rule is idiotic. 

its mostly the meh against Chelsea.. For all those millions spends on great players.. Their football is pretty meh.. Sure sometimes they play beautiful but a lot of time they park the bus and go for a counter.. With all those great players we expect a bit more.. Especially against 10 men.. psg was playing better that shouldn't happen?.
