England's Jos Buttler on Wednesday said he will discuss his future as white-ball captain with team management after his side lost to Afghanistan to crash out of the Champions Trophy.

England cannot be faulted for effort at the World Cup but the team are lacking confidence and must start imposing themselves on the opposition, coach Matthew Mott said, after the defending champions lost two of their first three matches in India.

Afghanistan pulled off one of the greatest World Cup shocks on Sunday when they defeated defending champions England by 69 runs in New Delhi.

Flamboyant opening batsman Rahmanullah Gurbaz hit a blistering 80 as Afghanistan, buoyed by some lusty late hitting, made 284 against defending champions England in the World Cup on Sunday.

Afghanistan coach Jonathan Trott admitted Saturday that his team "get it 70-80% right" but need to find an extra gear quickly if they are to end a demoralising run of 14 successive World Cup defeats.
