When we are organised on the pitch, it is easier to play in defense.
How do you mark Ronaldo? You try not to leave him alone and don't let him shoot on his right foot. As for Messi... you just make the sign of the cross!
Your No. 1 priority as a defender is to keep the ball out of the back of the net.
Good keepers sniff out attacks whether with the feet or a throw out.
Keeping up your concentration is one of the hardest tasks when you're a centre-back because a team like Bayern tend to dominate and can give you sense of false security.
I block shots and stay out the way.
I've become accustomed to playing against four defenders throughout my career, but in Italy, I have to play against five.
You don't want to be giving away free-kicks in the penalty area.
If you concede a goal, it can be up to seven or eight mistakes leading up to it but, obviously, as a goalkeeper you have to accept it has gone past you.
You're always supposed to follow-up any cross or whatever towards the goalkeeper.
Sometimes journalists say that goalkeepers can do a little more when they play against Messi, but I see it in every training: it does not matter where you place yourself; he's going to shoot to the other side.
When you come to a place like Old Trafford, you have to defend, and the system is in place for perfectly good reasons.
