We have got one more point to 'discuss' !!
Karthik should have tried to give strike to Sachin and facilitated Little Master to reach the milestone.
But it was more important to win the match and Sachin should be happy with the 'winning knock'
If he was keen on 100, he would have accelerated the scoring rate when in 80's, as commented by Sunil Gavaskar
Perhaps, Sachin (his critics may not beleive) actually does not play for records!
Good for him, for the game and the spirit of any team Sport
