On top of that Iyer's captaincy is also not looking great. He is unable to motivate the team and to keep the morale high. Maybe they need a new captain for the final match.
DC performed exceptionally well during the first half of this edition and that is the reason why they are in the final. That said, I would still give the credit to Kagiso Rabada and Anrich Nortje for this achievement. It was their high-quality depth bowling, which enabled DC to win so many matches. I would say that the captaincy made hardly any difference during this phase.
The stonis is also playing great from the previous match. The match between SRH and DC was a do or die one and they have performed well. I believe today also they will blast.
