I came across this nice article while browsing cricinfo. I think he is the best keeper in the world right know.

I am glad he has chosen his role model in Ian Healy. He was another brilliant keeper of his era, perhaps the best during that decade. Prasanna has also improved his batting a lot nowadays and that should confirm his place in the test team, while I think Kaushal Silva should be made his understudy.
