I personally had the opportunity to watch the game between Zagreb and Chelsea. It was lack of pace that causes their down fall. Just us you said, the counter was quick and the defenders of Chelsea couldn't stop the striker with his speed. it was normal that the Keeper couldn't have done anything about the goal.

Juventus I believe could have done much better than what they did. They had a lot of great opportunities they could have equalize in the second half however they missed. I hope they make use of those opportunities in their home grounds.

Real Madrid had it so nice and as you said, Benzema absence resulted in three goals then assuming his presence. I believe it could have been more than three.

Thanks for sharing.
