Is it more than just possible all the 'favourites' could miss out on the CL semis?

No way for barcelona and bayern to get knocked out at this stage , forget about it... Bayern will win at Benfica that's for sure , they won't make the mistake they made vs Juve... Barcelona have the best attack in the world with MSN , this attack can no way don't score a minimum of two goals , about Real madrid , it's a big possibility for them to get knocked out because they underestimated a very well organized team in wolfsburg , and the second leg won't be easy for them since they are facing a very well organised german team who are willing to qualify to the semis and will do everything for it , as well as PSG, they will win in Manchester , although it will be a very tight game , but manchester city's defence can't okay with an attack formed by ibrahimovic , di maria and cavani , we all saw ibra's goal... so i say bayern , barca, wolfsburg and PSG will qualify...

Yes very possible, Bayern have been poor away from home in the CL in recent seasons.. Real are 2-0 down and without an away goal it means they'll have to defend very well to stand a chance of going through, and their defence is old and mistake prone!..

Atletico have a good record v barca and city have two away goals, I think at least two of the favs will be eliminated!..

That is an interesting point.

Imagine, Wolfsburg, Benfica, Atletico Madrid and Man City in the semis. I would go for Atletico Madrid to win the Champions league.

Well it was never going to be easy for Barca vs Athletico but a 2-1 win is pretty good. The rest botched their games up

yes
