Dubai: International Cricket Council (ICC) chief executive David Richardson has said it's difficult to guarantee considerable number of games for leading Associate teams in their bid to qualify for the 2019 World Cup in England.

Richardson's view comes after ICC decided to reduce the number of teams participating in the 2019 World Cup from 14 to 10 with the top eight sides in the One-Day International (ODI) rankings till Sep 30, 2017, qualifying automatically.
