Akhtar is considered the fastest    bowler ever in the history of cricket. He was    the first bowler to break the 100mph barrier as well, which   he did twice in his career. Akhtar made his    Test debut in November 1997 as an opening fast bowler in the side   of pakistan and played his first one-day international three months later. Akhtar’s career    stats are impressive   in both forms   of the game, but what’s not so great is how frequently he wasn’t available for Pakistan 178 wickets in 46 Test matches and 247 ODI wickets in 163 matches. And his averages    in both forms are the fourth  best for any Pakistan bowler who took more than 150 wickets.very dangerous bowler shoiab akhter palyed his bye bye match against austrlia in world cup
