Ex-Indian cricketer reveals instructions before Pakistan match in 80s

He was denied wickets by former Pakistani umpire Shakoor Rana.

Former India spinner, Maninder Singh, has revealed details of biased umpiring during India's tour to Pakistan in 1982-83 during an interview.
It was Singh's debut series where he managed to take only 3 wickets from five Test matches as he was denied wickets by former Pakistani umpire Shakoor Rana, he said in an interview with ESPNCricinfo. Speaking about the series in which Pakistan won the 6-match Test series 3-0, Singh said, "I played five out of the six Tests, got only three wickets. Because it was their umpires, there was no chance of getting lbw, caught-behind, caught at silly point."
He further said, "At one stage, I appealed for a catch at silly point against Saleem Malik, and late Shakoor Rana sahab said, "Aaja, aaja, ethe sirf bowled kar, ethe ohiyeo wicket milegi." (Come back, you need to get batsmen bowled, that's the only way you'll get a dismissal here), Singh said.
Singh ended his career with 88 wickets in Test cricket and has over 600 wickets to his name in first-class cricket, picking up 66 wickets in 59 ODIs for India.
