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.

I always said in my career as a footballer, I owe everything to Newell's. But as a coach, I owe everything to Paraguay.

If you have removed those people and situations that make your life more drama-like, then you're definitely a success. After all, who doesn't enjoy a quieter home and workplace?

The old university attitude of 'publish or perish' has changed. Students and academics are realising that institutions such as Imperial College are also wealth-generators. It is very satisfying to be in a university where you have the freedom to innovate and yet know that there is a path to translate your work into industry.

I used to do films for money earlier. I never knew what perception meant. I didn't give too much attention to scripts. It was either to buy a house or to buy a car. There was a certain frivolity to the way I used to pick up things. I wasn't taking my career seriously.

To achieve the kinds of innovations needed to tackle the climate crisis, government must not shun the private sector, but rather must work closely with industry and our nation's great research universities.
