1. Rashid Khan
Even though Afghanistan might be the last team to qualify for the World Cup but they have the best wrist spinner in the business. Rashid Khan is current the No.1 T20I bowler and No.2 ODI bowler in the ICC Rankings. We have all seen how dangerous he can be in the IPL for the last two years. On his day, he can run through any side. He has the ability to pick up 2-3 quick wickets and turn the game. The 19-year-old leg-spinner is the quickest to 100 ODI Wickets in just 43 games. He has a phenomenal ODI record as he has taken 100 wickets in 43 games at an economy rate of just 3.96 and an average of just 14.4 with four 5 Wicket Hauls. Considering the success wrist-spinners are getting in England he might be the biggest X-Factor for Afghanistan in the upcoming World Cup.
