Australian skipper Ricky Ponting [ Images ] lost his cool when questioned about a catch he claimed during the final day of the ill-tempered second Test against India [ Images ] in Sydney [ Images ] on Sunday.

Ponting, fielding at silly point, turned back and dived for a looping catch offered by Mahendra Singh Dhoni [ Images ] but grounded the ball in his effort.

However, he didn't bat an eyelid before making an appeal, which was turned down.

When asked during the post-match press-conference about whether he caught the ball cleanly, an incensed Ponting took offence to the question.

"I claimed the catch and there was no way I grounded it (the ball)."

"If you are questioning my integrity, then probably you shouldn't be sitting here," retorted a furious Australian captain.

He, however, admitted the umpiring blunders marred the Test but hoped the match would be remembered for all the right reasons.

"We now go to Perth on a wicket and conditions that probably should suit us a lot more than it should suit the Indians," warned Ponting.
