"If players like him [Tendulkar] don't play the longer version of the game, Test cricket will die. I pray to God he continues to play Test cricket. I was very happy to know he has retried from ODIs. For me Test is education and the shorter versions are entertainment," Ranatunga told PTI.
Ranatunga, who guided Sri Lanka to their first and only World Cup title in 1996, said Tendulkar still has a lot of cricket left in him.
Asked whether Sachin was on a comeback trail after scoring two centuries in domestic matches, Ranatunga said the Mumbaikar, despite being 39, is a much better player than some of the younger Indians.
