Kolkata, May 7: Former Indian skipper Sourav Ganguly today said the youngsters' performance in Twenty20 cricket does not count for much until they prove their calibre in the Test format as has been done by seniors like him.

"Let's not jump up and down too much at their performance in Twenty20. As a player, I'd love to see them perform in five dayers and 50-over games. That's where the real test lies," he said.

"If you see my performance, I've scored more than 3000 runs in international cricket, which is more than any other Indian batsmen, ever since my comeback (in late 2006). But still I'm under the scanner," said Ganguly, the Kolkata Knight Riders captain in the IPL told a press meet.

Ganguly, however, admitted that captaining a Twenty20 side was different.

"Its different. It demands quick thinking. Captaining a Test side, you get a lot of time to make a comeback, but in Twenty20 if something goes wrong in three-four overs, you may be gone."
