What I've always wanted to know is was it actually Sarfaraz Nawaz who discovered reverse-swing, or did he learn it from Asif Masood or whoever.

There was a fair length of time when Imran Khan was said to have discovered it too, then he eventually decided it was time to say Sarfaraz had shown him it.

Either way, whoever it was probably is one of the biggest innovators in cricket history.
