Shane Warne has taken more Test wickets than any other bowler in the history of cricket.
The Australian spinner - who plays for Hampshire in England - is getting ready to try and win back the Ashes when England tour Australia in November.
But before then he offered some top tips to some lucky young players at a special spin clinic, and Sportsround went along to have a chat with him.
You seem to be enjoying this as much as the kids.
There are some good young players there too. It's a really good iniative from Mitre to get around the country, get around the counties and have a look at some bowlers and give them proper coaching from the ECB (England and Wales Cricket Board) and just promote cricket.
Especially spin bowling, which I'm a little bit biased towards.
As a youngster you were quite into Australian Rules football. What made you choose the more relaxed cricket over the rough and tumble Aussie rules?
I'm a gentlemen, and cricket's a gentlemen's sport. And I wasn't good enough at footie.
But I'm glad I did, because cricket's been very good to me. And I've thoroughly enjoyed playing it for 15 years.
I enjoy bowling, I'm still enjoying it now, and hopefully I can keep playing it for a few more years yet.
It's been brilliant for the kids here, was there anything like this when you were younger?
Not really. You used to have local clubs and the older players who were playing in the afternoon would come down and help you in the mornings.
In the afternoon you'd watch them play and then get to muck around on the pitch during the lunch break.
This is a fantastic thing for kids to do, to encourage them to participate in cricket, enjoy the sport and play and maybe find some good young spinners.
As an Aussie, playing in England, it's obvious how important the Ashes are. Your squad has recently been on a "boot camp", what was that like?
It was tough. A get together for the whole squad.
It was something a bit different. We had to push cars, we had to run up hills, carry water cans, sleep out in the middle of nowhere. That sort of stuff.
And do you think that will help with the cricket?
It might, who knows?
I think it's brought the guys a lot closer together, so I suppose it was worthwhile.
The Ashes were a big deal here last summer, what's the feeling like at the moment back in Australia?
It's a very anticipated series. Everyone's is pretty excited about it.
Last year England won for the first time in about 20 years, and they deserved to win because they played better cricket.
But since then they haven't played that well and had a few injuries and we've won 11 out of 12, so we're pretty confident in our own game.
Once the Ashes start it doesn't really matter what happened before. Both sides are going to be up for it and I think it's going to be a really good series.
