It's always difficult if you're coming into a new club and new league, especially the English one. It's a very demanding one, can be a very tough one.

At Ajax, we have a certain philosophy that is sometimes more important than winning - the development of players.

I share a special bond with Ajax. I think we are a special club. And we're known for our philosophy around the world.

I always said I wanted to finish my career back at Ajax, but I didn't think I was going to play for so long at such a high level, so that's not going to happen now.

Being under the microscope meant I was never given any slack. I still managed to screw up plenty in life, mind you, but in the things I really cared about - the legal work, or the stories I was telling as a writer, or the office I built in government - I wasn't left a lot of margin for error. It's kept me driven.

In my own career, I have always tried to treat my colleagues with respect and kindness, whoever they are, and am proud to have developed and mentored the careers of many excellent young scientists who will be tackling tomorrow's biological problems long after I have left the scene.

My fans have made all my career moments special for me. They are the ones that have gotten me through every single thing - good times and bad, they are who I go to and lean on. I am very thankful for that.

Sooner or later, The Rock's going to get tired of that empty space on his mantle where an Oscar should be, and that's when I'll get the phone call for the buddy movie that finally makes his career.
