When South Africa skipper Faf du Plessis indicated that the visitors had left no stones unturned while preparing for this series, not many in Bangladesh expected to see the team using a drone to analyse the visitors' performances.

Now that's not a scene that one gets to see every day at the Sher-e-Bangla National Stadium.
