Karachi, Aug 13 - The Pakistan Cricket Board (PCB) Thursday appointed former captain Javed Miandad as its batting consultant following the national team's disastrous tour of Sri Lanka this summer.

PCB chairman Ijaz Butt said Miandad has been asked to help Pakistan's struggling batsmen ahead of the ICC Champions Trophy that gets under way in South Africa from Sep 22.

'Our performance in Sri Lanka was very disappointing and the main reason behind it was our batting failures. That is why we have decided to get help from Miandad who is one of the world's greatest batsmen,' Butt said at a press conference.

Pakistan lost the three-match Test series 0-2 after two inexplicable batting collapses in Galle and Colombo. They also went on to lose the first three One-day Internationals before making a comeback to win the last two ODIs and the one-off Twenty20 International Wednesday.

Miandad is Pakistan's highest run-getter in Test history. He is currently serving as PCB's director-general.

The PCB has also asked Miandad to help the country's under-19 team which will be featuring in the youth World Cup to be held in New Zealand next March.
