The Indian Test squad arrived in Sydney yesterday defending themselves against an attack from one of their leading officials. Jaywant Lele, secretary of the Board of Control for Cricket in India, said India had no chance of beating Australia in their forthcoming three-match Test series.
"The wickets there will not help the Indians at all," he said. "There is so much bounce. Besides Sachin [Tendulkar], [Rahul] Dravid and [Saurav] Ganguly there is no one else who can bat there."
The Indian coach, Kapil Dev, hit back. "I have a lot of confidence in my team," Kapil said. "I don't think [Lele] can say that, but if he has that's his opinion and we can't change anybody's opinion. I have a team that has a talent and we can only talk about it at the end of the series."Reuse content
