All eyes will be on Virat Kohli’s leadership when India walk out at the Melbourne Cricket Ground for the second T20 International against Australia on Friday. Some glaring tactical blunders cost India dearly as they went down to the hosts by four runs (DLS) in a rain-truncated match.However, there will be no margin for errors against an Australian team that is starting to believe it can compete. It was only one match but the Aussies showed they can take the fight to their more fancied opponents. They were without Steve Smith and David Warner (as they will be for the rest of the Australian summer) against an Indian team which had won 10 of the previous 16 T20Is between the two teams. Australia had won only five.India had won the toss on a what looked like a belter of a pitch but their playing XI had raised some immediate questions. Yuzvendra Chahal has been one of the most successful bowlers in T20 Internationals this year – yet, he was left out as India went in with Krunal Pandya whose left-arm spin cost India 55 runs in four overs.With the bat, Krunal lasted only four balls so it would be unfair to really assess his role there.Read – Melbourne T20I: Will India replace Krunal Pandya with Yuzvendra Chahal?The Australian line-up is packed with hard-hitting batsmen and it could be worthwhile to try Chahal out. If Kohli does want to go in with a specialist all-rounder, chances are Washington Sundar might get a game.advertisementBesides, the batsmen really need to sharpen their game. Rohit Sharma and Virat Kohli had a rare off day but Shikhar Dhawan needed more support. Rishabh Pant and Dinesh Karthik revived India’s hopes but the former’s untimely dismissal made it more complicated for India.Also read – India have a lot of problems that need to be solved: Harbhajan SinghFor starters though, Kohli needs to get back to his usual No.3 spot.Australia, meanwhile, will be thrilled with their performance.
