Which t20 leagues has he played in whilst he moved to UAEBabar was not the best stats wise in this tournament. Usman Khan and Iftikhar both had far better stats.
Usman Khan has not made an international debut because he chose to move to the UAE and make money playing T20 cricket. Nothing wrong with that. He played 2 FC matches and didn’t perform and probably recognize he would not be able to make it as a Teat batsmen.
