'If I wasn't a cricketer I would trade in the derivatives market'

Talk us through that 221 against West Indies. What can you remember from that knock?

Describe your England career in one word.
Short.

There's a five-a-side football competition featuring all 18 counties. Who do you pick in your Kent team?

No.
Okay, I'll have me, Sam Northeast, Ben Harmison, Adam Ball and Sam Billings then.

Who wouldn't be near it?
Mark Davies.

And who's captain?
Myself.

What's the worst thing about captaincy?
Having to go to long media days.

You wear No. 4. Why?
It was the squad number I was given. If I'd thought more about it, I would have had 23 like Michael Jordan and Shane Warne.

There's a Sainsbury's at the ground.

If you could go back and give an 18-year-old Rob Key some advice, what would it be?

Trade in the derivatives market.

Peter Trego, who should have played for England, Ben Phillips, who should have played for England, and David Willey, who is going to play for England.

What do you order at Nandos?
It's quite expensive now. I've spent ages trying to get the black card. For years I had chicken with no chips but now I'd probably have chips and less chicken.

Adam Riley.
