He has his right to keep whatever signature he wants, as much as you have the right to have your own. Just get over it! Kumble was in the middle when Ishant came out with right handed gloves. How could he have said to Ishant?
And seriously, you want me to get to Ponting's slow retardness on the field when India were batting? Especially during that Tendulkar-Harbhajan partnership, Ponting was such a tensed crook that he was going here and there talking to his bowlers, making field changes and took up lot of time. If anything, it was due to Ponting's slackiness that took the match so long to complete.
