Analyse your statement again buddy . Firstly he is 33 years old so I don't think he has more than 6-7 years left for career . Secondly 1% improvement everyday means you are expecting another 50 years for him to score a century because they way he is playing , it will atleast take 50 years for him to score a century . Thirdly No scope of improvement is there since the last 3 years . In Test Cricket , he gets out mostly when ball comes towards 4/5 th stump and he tries to play cover drive. This is repetitive . Idk why he cannot leave that ball . He has been exposed now in International cricket . Teams know that when he is in the crease , try to bowl out of off stump and you shall get his wicket . That's why I said that BCCI should start looking for new players instead rather than to just rely on Kohli . And yes most important , He has a very good luck that is why we never won any tosses especially when we needed the most ( T 20 World Cup ( 2021 ) , WTC ( 2021 ) ) etc.
