Argentina against Brazil is the most important derby between national teams.
I really do not care that Messi isn't scoring every match. Leo always produces match-changing moments.
Messi's start to 2015 has been unrivalled. His efficiency in front of goal and the amount of goals he has scored cannot be bettered.
When you have the chance to finish off your opponent, you must do it. You shouldn't give them chances to come back.
That is the problem we have in Argentina: we do not sit down and think.
My happiest time was with Paraguay. Those were five years in which I managed to find happiness.
It is hard to enjoy life in a national team.
Messi's career is a cinema script.
Messi never wants to be subbed off, but it's my task to take care of him.
I didn't make any mark on Barcelona. It was a blip in my career in terms of what I did as a coach.
We should never have to do whatever Messi says. I did not pay attention to him, not even in the national team. But that is the myth that has been formed. But it is not just me: a lot of people have said it, but of course you won't believe it from me... It is not me who is denying it. The facts deny it.
I made some monumental mistakes with Barcelona.
Everyone wants to finish a project they start, but in the world of football, you cannot guarantee anything.
The national team requires a work commitment but also a personal one as well. To lead your country is something very different.
I have the advantage of having worked with Messi and Mascherano at Barcelona.
I was surprised by how little they knew about me at Barcelona. You can accept that from a supermarket cashier - but not from someone who works in football.
I would never risk speaking ill of Messi.
When we are operating in tight spaces and when the opposition are closing us down, players like Messi can help us to create openings.
There some players who show what they can do over 90 minutes and others who demonstrate it in 15.
Sometimes, it is logical that by analysing a player, one thinks it is better to play him in one place or another, but then, if he is good, you can be more flexible.
