I have nothing against Sachin Tendulkar, but I feel his time is over like Chappell; he's scored loads and loads of runnings and what not... but honestly speaking, for someone who's played 350+ ODIs and 100+ Test matches... how many of these big scores have come against quality oppositions at crucial times? That's a terribly small fraction, if carefully examined. In comparision to Lara, the West Indian genius has played tons of innings and very nearly made a difference on many occasions; every now and then you see when the team is struggling he comes, tries to hold one side up, scores a valiant 70/80 but can't do anything beyond that due to lack of support. I haven't seen much of that from Tendulkar, more so in recent years. Plus I believe his injuries have hindered his performances more than realised, and I really don't think he's as fit and sharp as required to compete consistently with today's pace of cricket. I'll go with what this Chappell say (definitely not what the other one does, though) and say for his sake, let him retire now. Because, if he plays on, what will he prove? It would just show that he is more concerned right now about his image to the public and that he wants them to remember only him... retiring now wouldn't be cowardice; it would be bravery, in fact, admitting to not being able to compete at this stage.
