All the time there are rumors and news that making test matches of 4 day, then making it day and night etc. but whenever you see the arch-rivals Australia and England playing everyone forget about every rumor and stick to their television.
Test cricket is the real test of a cricketer. In five days you have to survive or you have to show your supremacy over opponents. It’s a game of tactics and aggression.
Recent Ashes test series is the example of there is no need to bring changes in test cricket. Still everyone can’t even suggest whose going to prevail this year’s Ashes. It’s an even contest between big 2’s.
If ICC wants to promote test cricket and to make it more exciting they must take a step and schedule more bilateral series between arch-rivals like England and Australia, India and Pakistan, Pakistan and India series is missing from years last time they played in white uniforms in 2007. So such series should happen in test cricket for its survival.
