It was not luck as Ashwin said in his YouTube channel. We lacked strategy for finals. Surya, Siraj never performed like we wanted them to be(See the finals of Asia Cup, did siraj performed the way we wanted him to be). After Pandya was injured, Prasidh was brought in. Who does that? I mean who? Like to like replacement is needed. We didn't do that. There should be some surprise package every world cup. Inglis to me was surprise package for WC after Carey hit some 90s in South Africa. Kuldeep was ineffective. When ball was seaming and swinging, Rohit didn't give ball to Siraj. Yes, Shami picked up wicket of Warner, but after he beat outside edge of Head twice, it was needed to bring Siraj. But that didn't happen. After just 240, we needed to have some kind of strategy. See the full over Cummins bowled to Iyer in his dismissal(Till that time, Cummins hardly performed, wickets he got was not earned, but he earned that wicket). They properly executed it. After Gills dismissal, Rohit needed to stay on the crease. That didn't happen. When you scored runs of first two balls, why you need to take another risk. Communication was required which Virat didn't have with Rohit(The way Ishan did with Surya in last match).
