I am suprised everyone here is pointing DLS as the reason why GT lost the match. I am confident almost none have watch the match. DLS was the reason why CSK was struggling to chase the target in the last two over.
If you haven't watch the live match go on and watch the highlights. It is available for free on Jio Cinema. DLS was a benefit to GT as per my opinion as in 15 overs it is hard to chase a target of 170+. CSK won because of Sir Jadeja and not because of MSD or any other player. No one expected he would score 10 runs in the last two balls.
I have watched the match actually and I will say that the rain interruption took away the momentum from GT. That was the turning point of the match for me. Of course, the match had a lot of twists and turns. Of course, what happened in the last over was certainly great to see for any fans in my opinion. But if I say that the match would have had the same result as this if there was no rain, I would be lying.
But anyway it was certainly a very good match and the tournament had a very good finishing I would say.
