Afridi, who returned home after his team Hyderabad Deccan Chargers failed to perform well in the tournament, said the league had left him amazed after seeing the support and the interest from the public.
''Even though our team performed badly but still in our final game there was a big crowd out to support us and this shows the interest the IPL has created,'' he said.
''I can't say if 50-overs cricket would be affected by the popularity of Twenty20 but certainly Test matches would be hit hard as people are more interested in seeing instant and exciting cricket,'' he added.
The 28-year-old, who failed to live upto expectations in the IPL, admitted that he has been ignoring his batting for bowling.
''I know I disappointed and let down my fans with my batting failures. But now I am going to pay attention to my batting once again and I am confident I can get back into form soon.
''I am l looking forward to playing in the tri-series in Bangladesh against India it will be a good opportunity to make amends,'' he stated.
