Ashraful, I think is one of the most talented batsman in the world today, remember he scored his first test century against Sri Lanka when he was only 16, the youngest centurian ever against the likes of Murali and Vaas. Even Tendulkar could not score a century at that age although he made his debut at the same age. Ashraful needs to work hard and he still has time as he is only 20. Watch out for him in two to three years.
