England has emphatically dismantled Twenty20 cricket’s traditional powerhouse, delivering India a sobering reality check as it begins the two-year task of building a team capable of reclaiming the T20 World Cup.The two-time T20 world champions in blue were listless in all facets of the format as England sealed a 4-0 series win after India conceded over 250 runs for the first time in a T20 at Southampton in the final game on Saturday.England not only dominated all the Indian Premier League big hitters like Abhishek Sharma, Ishan Kishan and the newly crowned captain Shreyas Iyer, but Harry Brook’s men also shattered the confidence of 15-year-old prodigy Vaibhav Sooryavanshi.The selectors’ road map for Sooryavanshi’s international debut after a bumper IPL season this year backfired big time. The left-hander was twice bounced out by his Rajasthan Royals teammate Jofra Archer and could manage only a combined score of 42 runs in three games.The shortcomings in this Indian team -- without Jasprit Bumrah, Hardik Pandya and axed world cup winning captain Suryakumar Yadav — was quite evident when Ireland shocked them for a dream 2-0 win at home prior to the whitewash in England. The selectors left out Gujarat Titans skipper Shubman Gill, who could now come into the reckoning for the next T20 World Cup in Australia and New Zealand.
