Pakistan all-rounder Shahid Afridi has revealed that he will retire from one-day international cricket after the World Cup.

The 34-year-old intends to focus on his Twenty20 career when the tournament comes to an end, as he looks to help Pakistan to their second title in the 50-over format.

"I am the first Pakistan player to be able to announce his retirement properly and on a high. I always wanted to do this having seen the problems faced by other bigger players in the past," Afridi told reporters.

"Having taken a decision it is a big burden off my mind and I am confident I will be able to focus on giving my best in the World Cup.

"It was not an easy decision to take and I think many of my seniors also found it difficult to go out at the right time. But no one is indispensable in cricket and I am sure sooner or later someone will take my place in ODIs as well."

Pakistan start their World Cup campaign against arch rivals India in Adelaide on February 15.
