Answer 8

At the start 64 teams would play against 64 teams.(128). From that 64 will be eliminated and 64 selected. Out of 64 there will be 32 matches and 32 selected. Out of 32 there would be 16 matches and 16 selected. Out of 16 there would be 8 matches and 8 selected. Out of 8 matches 4 selected. Out of 4 matches 2 selected and last final match out of two one would be selected.
So total matches = 64+32+16+8+4+2+1 =127
