Anyone heard of a certain KP? I know he played school cricket and a bit of club in SA but he developed, matured and primed through the county system, the English system and went on to become a legend for England. He should count.
And Freddy ,for all his comedy these days, was once a dangerous, 95mph fast bowler who could hold a bat pretty well too. Both are greats.
Of course, I don't think England have the same quality of great players over the last 50 years, as Australia, Pakistan and the Windies.
I could probably make an XI for each of those nations, with undisputedly great cricketers. If I were to do the same, I would probably be stretching the definition of great when it comes to the likes of Steward, Willis, Swann, Underwood,...certainly English greats and lauded as Gods here in the UK but not players regarded as greats across all nations and all eras.
