Isn't it strange that he retired from the shorter format of the game but will keep on playing the shortest format IPL?
Anyways even if he retires from international cricket, he will be playing IPL for many years. Also when you have no pressure from the Int. cricket, sometimes you may perform well in the domestic cricket or franchise-based formats.
Kohli performance has gone down after his marriage - I believe he has started believing he is a bollywood star too and he must focus on his looks and career rather than his performance - I have seen one of the interviews where he said he will not eat pakora because he has achieved his fitness after huge struggle - but where did his performance go - time to eat pakora now.
