Mascherano's impact as a leader is more important inside the squad, and Messi's leadership is more important in the pitch.

At the beginning of my career, I wasn't coaching players like Messi.

I didn't make any mark on Barcelona. It was a blip in my career in terms of what I did as a coach.

Messi's career is a cinema script.

Involvement in my kids' sports teams is something I have made time for over the years. I've also been able to coach all three of them in baseball and basketball, something that has strengthened our bonds and given me indescribable joy. I wouldn't trade it for anything.

We are both drawn to surreal situations so the writing was a joy.

The first country to adopt happiness as an official goal of public policy is the tiny little country of Bhutan in Asia near China and India.

I came from a place where there wasn't a lot of joy.
