Bradman,Sobers,Gavaskar,Border,Ponting,Sachin,Lara all are great batsmen.But Viv was the biggest match winner among them and the impact he created was an unexplainable one.He could play any kind of game.A long innings or a quickfire 50 according to the situation could face any kind of bowling on any surface.If T20 was introduced during his prime days he should have broken many records.
