Not sure about the second part of your question, but I seem to recall that bookings carry over to the round of 16 and are then wiped out in the quarters. I think I heard that Verrati for PSG last night, when he got booked, would miss the return leg.
Yeah, I think that sounds about right.
Just did a bit of digging.
In the group games for Madrid
Essien got booked v Ajax away
Ramos and Alonso were booked v Dortmund away
Ramos and Alonso were booked v City away
Arbeloa two yellows v City away
Ronaldo and Carvalho booked v Ajax at home.
Ramos, Alonso, and Arbeloa all missed the Ajax game so I assume they now have a clean slate and the only ones carrying bookings over are Ronaldo, Essien and Carvalho.
For us:
Evra, Vidic and RVP all booked v Galatasary at Home
Rio booked v Cluj away
Smalling booked v Braga away
Rafael booked v Galatasary away
Scholes booked v Cluj at home.
So looks like we have more to worry about tonight on that front than they do.
