There are some agents who do a good job looking after players but there are others who stifle and mollycoddle them.

Something interesting has happened over the last 10 years in the Premier League. Players who once would have been discarded as expensive and too old have become important parts of title-winning squads.

As football gets more globalised, it's probably more important than ever to have one or two players in your team who have grown up in the same streets or been to the same schools as the hard-core fans.

It is one of my pet hates when I see players who have agents who do everything for them. They don't know how to set up their own bank accounts, they don't know what they are spending their money on and they can't make their own decisions.

Gina Carano is a great athlete, and I'd be happy if she returns to MMA - doesn't matter if it's against Ronda.

Frankly, I'm not sure how far I would get if I attended public school today. It's not just that public schools aren't producing the results we want - it's that we're not giving them what they need to help students achieve at high levels. K-12 education in the United States is deeply antiquated.

I teach at the Stanford Business School, and about half of my students are foreign, many of whom, I hope, will stay and build businesses in U.S. But I must tell you that they also have opportunities to come back to India and start great companies and operations.

The Sistine Chapel is an extraordinary work of education - it lays out all the early books of the Bible.
