Whether played over 50 or 20 overs, the biggest attraction of this tournament has always been the high-octane Indo-Pak rivalry. A look at five memorable battles...KHANNA THE SURPRISE HERO (SHARJAH, 1984)A top-class Pakistan team was tipped to beat India when the inaugural Asia Cup took place in April, 1984. But a fine knock by wicketkeeper-batsman Surinder Khanna (56 off 72 balls) helped India get to 188-4 in 46 overs on a difficult wicket. Roger Binny and Ravi Shastri then helped bowl Pakistan out for just 134 in 39.4 overs. Khanna effected two stumpings too. Scores: Ind 188-4 in 46 overs (Surinder Khanna 56, Sandeep Patil 43, Sunil Gavaskar 36*) beat Pak 134 in 39. 4 overs (Mohsin Khan 35; Roger Binny 3-33, Ravi Shastri 3-40) by 54 runs
