Former Australian captain Ian Chappell has said that Pakistan captain Shahid Afridi is "a bit crazy" and should not be in charge of the Pakistan World Cup team.

"When you have a captain who is a bit crazy, crazy things happen. To me, he was never the right guy to be in charge and that's only part of the reason, but it's one of the reasons why with Pakistan you never know what's going to turn up," Fox Sports quoted Chappell, as saying.
