Virat Kohli's poor performance with DRS continues...

In the ongoing series of 6 ODI matches in between India and South-Africa,while the first match was in progress Indian bowling attacked clicked and ultimately got South African batting attack under pressure and got wickets.
In the 36th over of the South African batting , Jasprit Bumrah attempted a yorker and ended up getting it down the leg side. The man behind the wickets(Dhoni) guarded it behind the wickets and while both the bowler and keeper weren’t interested in an appeal Kohli looked very excited and came running across the pitch appealing.
On the other side Rohit Sharma also seemed to be saying not to have a review but Kohli took the DRS and ended up wasting it and been beaten by the umpire's decision.
Now the thing to be considered is that the Ex-Captain of Team India was very well-known for his reviews and fans also are waiting for Kohli's efficiency of having DRS to get to that level.
