KOLKATA: In the World Cup, it always gets tougher with every passing stage and now that India are in the knockouts, the difficulty quotient has gone up a notch higher.Go Beyond The Boundary with our YouTube channel. SUBSCRIBE NOW!England, their opponents in the second semifinal in Mumbai on Thursday, flew a bit under the radar during the early games but India head coach Gautam Gambhir insisted his team will have to be at its best to beat them on Thursday.Theyre a world-class team, Gambhir said. Theyve got a lot of quality players and Wankhede is a tough venue. Hopefully we can turn up and get another opportunity to do something special. Hopefully, well play our best game and keep ticking all the boxes. Well need a special effort to beat a quality side like them.I dont believe in all this peaking-at-the-right-time thing, Gambhir said. Youve got to win every game when you represent your country, as simple as it can get. Its a short tournament, so youve got to try and play your A game every time and its a format where you cant take any opposition for granted.The current-day strategy involves a lot of data analysing and poring over videos, but for Gambhir, instincts still hold away above everything else. Ive never seen the data, he said. I dont even know what data is all about. I absolutely do not believe in it, because I feel its more about instinct. T20 cricket is about instinct and backing your instinct. Whatever knowledge I have about the game and T20 format, I try and probably give it to the captain, try and help him out as much as I can.Batting coach Sitanshu Kotak echoed Gambhir in saying that facing England wont be easy. We have to turn up and execute, he said, adding, Abhishek Sharma has been very successful against England. Itll be a tough game but I think well do well.
