I think we both know the level of attacks they face in French League? Cahill-Terry have faced Suarez, Rooney, and what not.PSG have a mean defensive record at home. And they are a fearsome duo. Certainly a more complete one than Chelsea's duo.
Everyone I know how watches the French League saus Marquinhos hasn't been all that good. He's certainly been good for someone 18 years old playing at this level, but that does not mean he's been good at the highest level.
And if it was just one guy saying that, I might check myself but there were more and they're pretty credible, to me.
Also, Mourinho knows how to set his team up defensively, **** we've even got defensive wingers to play if we need to.
