Well, as vcs says, there is maybe a small amount of personal bias involved.
Atherton, because he was the player when I was growing up that a lot of our fortunes rested on. He was such a stubborn player and had masses of pressure with the captaincy from a very young age. I also thought he was very good looking so I put pictures of him all over my walls, and kept a scrapbook of newspaper cuttings of articles about him. Basically, I got into cricket because of him, and he was my second biggest teenage obsession. (Graham Coxon was the first, btw!)
Nasser, because I think he was the turning point for England. Vaughan may have got the plaudits but imo it was Nasser who really changed things. I also loved his fiery nature and I find him great as a commentator. Again, he's also quite hot.
Watto, because I just love the drama, the ups and downs, all the emotion. I just think he's brilliantly bonkers, because he seems to have a Gunther-esque personality on the field, and in interviews he's so polite and shy. And he's just about the cutest bloke I've ever seen.
