As everybody knows that this high-voltage is nothing less than "final" when 2 arch rivals are playing face 2 face ! The presence of 'political heavyweights' of both the country only adds to the already building-up pressure on players of both the team 2 perform well beyond own capacity !
Its all about the mind-game in the penultimate season of the game, where Dhoni coolness matters more than his game and at the same time Afridi 'bats' will do better than his 'spin'. The home-team advantage as well as pressure is always more. The situation is more difficult when nation is playing the 'game' too beyond the pitches !
Finally, in the end no good or bad team/performance matter nor there should be any 'patriotism' beyond game ! And those nerve will be in control , the team will not only reaches final, but can emerge as clear Winner too !!!
